Earlier this week, I found myself dissecting an embargoed briefing video frame by frame, like a JFK obsessive trying to squeeze meaning from the Zapruder film. I鈥檇 just had an interview with three top scientists from Nike鈥檚 Breaking4 team, the group tasked with coordinating Faith Kipyegon鈥檚 attempt to run the first women鈥檚 sub-four-minute mile later this month. I got some answers, but I still had some big questions, and I hoped the video might reveal some clues.

Ever since back in April, there鈥檚 been speculation about how Kipyegon will be able to make the leap from her current world-record time of 4:07.64 to sub-four. It鈥檚 reminiscent of the uncertainty that surrounded the company鈥檚 Breaking2 project in 2017, when they announced that Eliud Kipchoge and two other runners would aim for a sub-two-hour marathon at a time when the world record was 2:02:57. Such a big leap鈥�2.4 percent, compared to the 3.1 percent Kipyegon needs鈥攕eemed implausible, and most observers dismissed the announcement as an overhyped publicity stunt. Then Kipchoge ran 2:00:25 (and later broke 2:00 in another exhibition race). So the commentary this time has been more circumspect. Nike must have something up their sleeve, the thinking goes, otherwise they wouldn鈥檛 be sticking their necks out.

The three experts Nike made available to discuss the project were Carrie Dimoff from the Innovation Footwear team, Lisa Gibson from the Apparel Innovation team, and Brett Kirby, a physiologist at the Nike Sport Research Lab. The choice of experts tells us which levers the company hopes to pull in pursuit of a four-minute mile. Here鈥檚 what they revealed.

The Shoes

The least surprising news is that Kipyegon will be wearing bespoke racing shoes, dubbed the Victory Elite FK, designed to make her faster than she was in the Victory 2 spikes she set her current record in. How much faster the new shoes will be is hard to determine, though.

When Kipchoge ran Breaking2, he did so in a radical new shoe design featuring a curved carbon fiber plate and a thick layer of ultra-resilient midsole foam. Those shoes came with a lab-tested promise: they made runners four percent more efficient, on average. That kind of efficiency difference is capable of reducing race times by two to three percent. In other words, the shoes alone made Breaking2 plausible.

Quantifying the benefits of Kipyegon鈥檚 new spikes is harder for a couple of reasons. One is that you can only measure efficiency accurately when you鈥檙e running slower than your aerobic threshold. At faster speeds, like your mile race pace, you start relying on 鈥渁naerobic鈥� metabolism, which doesn鈥檛 require oxygen. Since running economy is calculated based on how much oxygen you鈥檙e consuming, our go-to measurement techniques are no longer accurate once you go anaerobic.

Even if it was possible to measure running economy at mile speed鈥攊f we knew that, say, the new spikes were 4 percent more efficient than previous models鈥攖hat wouldn鈥檛 tell us exactly how much faster Kipyegon could run. For marathons, efficiency is crucial, because in a long race you鈥檙e inevitably going to run low on fuel. In a mile, you don鈥檛 have enough time to empty the tank. Efficiency is still useful, but it鈥檚 not the race-defining factor is it in longer events.

For sprinters, fuel efficiency is basically irrelevant. Instead, they鈥檙e concerned with how effectively they can transmit force to the ground to propel themselves forward, energy costs be damned. Milers are somewhere in the middle, needing to find a balance between efficiency and force transmission. The data Dimoff and her team collected on Kipyegon鈥檚 various shoe prototypes used a force-sensing treadmill to figure out how much power she could transmit to the ground, as well as biomechanical analysis to estimate how much energy she was burning. They didn鈥檛 share any numbers, but they saw measurable improvement in those parameters as they fine-tuned successive iterations of the new Victory Elite FK design.

More generally, there鈥檚 not a lot of data on the new generation of superspikes, which, like the road-running supershoes introduced in Breaking2, tend to have a midsole unit with lightweight, resilient foam, often alongside a stiff carbon fiber plate. The best info we have on such spikes comes from Wouter Hoogkamer and his colleagues at the University Massachusetts, Amherst鈥檚 Integrative Locomotion Lab. They that runners tended to go about 2 percent faster in superspikes than in conventional spikes.

An interesting detail in Hoogkamer鈥檚 data is that men ran faster in spikes that had a carbon plate in addition to the foam midsole. For women, on the other hand, the carbon plate didn鈥檛 make any difference. That suggests that the generic plate used in the test shoes might have been too stiff for the women to exert enough force to take advantage of its propulsive properties. If that鈥檚 true, then the extensive fine-tuning that Nike is doing to create a shoe specifically tailored to Kipyegon鈥檚 stride has the potential to make her faster than an off-the-shelf shoe.

With that preamble, what does Kipyegon鈥檚 new shoe look like? In some ways, it鈥檚 a lot like the that she wore last year. It has an air pod (a bubble designed to compress and then spring back to return energy) under the forefoot, a wedge of ZoomX foam under the heel, and a curved carbon fiber plate running under the length of the sole. They鈥檝e pulled out all the stops to use thinner and lighter materials for the upper, and the spikes themselves鈥攕ix rather than the four in the Victory 2鈥攁re 3D-printed titanium to reduce weight. One of the prototypes they tested was a barely-there 83 grams, compared to a listed weight of 136 grams for the Victory 2. Based on the rule of thumb that every hundred grams of shoe weight burns an extra one percent of energy, that’s half-percent edge in weight alone. Thanks to all this trimming, the Nike team has been able to make the forefoot air pod three millimeters thicker, which gives a little more energy return over the Victory 2. According to Dimoff, the air pods return more than 90 percent of the energy you put into a given foot strike.

World Athletics rules limit the stack height (i.e. the total thickness of the sole) of track spikes to 20 millimeters. Dimoff said the shoe will conform to this and other requirements. In fact, in Kipyegon鈥檚 sole track outing of the year so far, a 1,000-meter race in 2:29.21 at the Xiamen Diamond League race in April, she wore a version of the new shoe which had gone through the World Athletics approval process (I鈥檓 pretty sure it鈥檚 the Dev 611 shoe listed ). That certification process takes about 30 days; since Dimoff鈥檚 team wants to continue making tweaks right up to the last minute, they won鈥檛 be submitting the Breaking4 shoe for certification, but expect that it would pass if submitted. That, on its own, is enough to guarantee that whatever time Kipyegon runs won’t count as a world record, whatever other rules they do or don’t bend.

The Apparel

There鈥檚 lots to say about the 鈥淔ly Suit鈥� Nike is designing for Kipyegon, but I鈥檓 probably not the right person to say it. A lot of the focus for Gibson鈥檚 team is making sure that Kipyegon feels good鈥攃omfortable, confident, unconstricted鈥攚hile she runs. I鈥檓 a big believer that these factors are important, but they鈥檙e very hard to quantify.

Of course, the team did do a ton of aerodynamic testing, both in the wind tunnel and with simulations. The fabric has 3D-printed Aeronodes: little bumps of varying size distributed across the garment to create mico-eddies that reduce the turbulence of the air flowing past Kipyegon. The suit comes with arm sleeves with articulated elbows to minimize creasing, which also extend forward to cover the knuckles, where some of the most turbulent air can be found. It鈥檚 got a headband, the running equivalent of an aero helmet in cycling. Nike is also debuting a special new sports bra that鈥檚 3D-printed out of ultralight TPU, a polymer that鈥檚 better known to runners as one of the midsole foam materials used in supershoes.

How much does this stuff matter when you put it all together? Presumably Nike has a wind tunnel estimate comparing runners鈥� energy consumption with the new suit compared to business-as-usual, but the researchers didn鈥檛 share it. For Breaking2 in 2017, one of Nike鈥檚 apparel specialists told me they figured they would get somewhere between a second and a minute over the course of the marathon from all the aerodynamics they鈥檇 worked on鈥攁nd that this was crucial, because if Kipchoge missed the two-hour barrier by a second, they would never forgive themselves. Gibson told me something similar about the Breaking4 suit: 鈥淲e didn鈥檛 want to leave anything on the table.鈥�

Everything Else鈥ncluding Drafting

Adding up the hypothetical numbers for the shoes and clothing, a four-minute mile still seems far away. I was imagining some pretty far-out scenarios when Nike first announced this attempt, like a specially built track with perfect bounciness and optimized curves, but Kirby shot those ideas down quickly. The race is going to take place at Stade Charl茅ty in Paris sometime between June 26 (the most likely date) and June 28. They鈥檙e not building anything new or modifying the stadium or track surface in any way. They chose it because, based on a review of decades of environmental data, it鈥檚 likely to have great weather and in particular a low likelihood of storms. It also helps that Kipyegon has set a couple of world records in that stadium: 5,000 meters in 2023, 1,500 meters in 2024.

I asked about nutrition and supplements. For example, Kipyegon has reportedly tried baking soda in at least some of her prior races. Kipyegon has her own nutrition team through her sports management agency, according to Kirby, so Nike isn鈥檛 making any changes to the regime she鈥檚 already on. They are, however, monitoring and analyzing her training. What sort of insights does that provide? Kipyegon is strongest over the 1,500 to 5,000-meter range rather than over shorter distances like the 800 meters, Kirby noted, so the training analysis indicated that she needs to develop her speed鈥攐r, as physiologists would say, her anaerobic capacity. Kipyegon鈥檚 legendary coach, Patrick Sang, probably didn鈥檛 need a supercomputer to uncover this insight, but perhaps the analysis is helping him figure out just how much speedwork is enough, and how he can add it in without compromising her endurance.

That leaves drafting. After Breaking2, most of the post-mortems attributed Kipchoge鈥檚 big leap in performance to some mix of supershoes and the pacers who surrounded him and blocked the wind for almost the entire race. Some thought his success was virtually all pacers; others thought it was virtually all shoes, and that debate continues to this day. Breaking4 will give us another datapoint. In this case, the shoes don鈥檛 seem like a radical break with the shoes Kipyegon and others have already been wearing, so it seems to me they must be relying on drafting. Some recent research from Rodger Kram鈥檚 group at the University of Colorado, completely unconnected to the Breaking4 initiative, suggested that drafting alone would indeed be enough to get Kipyegon to sub-four.

How will they do it? Nike鈥檚 official line is that they haven鈥檛 decided yet. How many pacers will there be? TBD. In what formation? TBD. Will they be men or women? TBD. Will they run the whole race or, as in Breaking2, sub in and out partway? TBD. Will there be pacers at all, or might she just run a solo time trial guided by nothing but pace lights? TBD. I can believe that they鈥檙e still fine-tuning the details, but I have a hard time believing all those options are still on the whiteboard.

That鈥檚 where the frame-by-frame video analysis comes in: In one of Nike鈥檚 briefing videos about the science, in the background at what appears to be the forest-shrouded track on Nike鈥檚 main campus, you can see glimpses of what looks like drafting experiments going on. A runner clad in white circles the track with something鈥攑erhaps an air pressure or wind sensor?鈥攕trapped to their chest. Sometimes they鈥檙e alone; sometimes there are two other runners in black singlets directly and diagonally in front of them; sometimes there are three. In one shot, five pacers form a half-diamond in front, beside, and behind the central runner.

Which configuration will it be? Who knows. My best guess, triangulating between physiology and optics, would be either one shift of five men taking her all the way to the finish, or two to three shifts of five women taking turns. But I can鈥檛 blame the Nike team for not spilling all the details in advance. I would probably do the same in their shoes. However you add up the numbers, getting to sub-four is going to require a stupendously, perhaps even magically, good day. On his best days, Eliud Kipchoge seemed to be able to summon some magic from a deep well-spring of self-belief that transcended all the shoe tech and pacers and hyper-optimized conditions. Nike is clearly hoping that Kipyegon will be able to do the same. But the thing about magic is that, if you talk about it too much, it tends to disappear.

Faith Kipyegon鈥檚 Breaking4 race is scheduled for the evening of June 26. I鈥檒l be providing on-the-ground coverage from Paris before, during, and after the race, so stay tuned.

Best Multi-Pocketed Shorts

Janji W’s 5鈥� Pace Short

Sizes: XS-XXXL

Pros and Cons
鈯� Lightweight, comfortable fabric
鈯� Well-placed storage pockets
鈯� No zippered pocket

The Janji 5鈥� Pace Shorts are so comfortable that they converted more than one tester who prefers the modesty of looser-fitting styles from 鈥渘ever-ever would I wear skin-tight shorts like this鈥� to 鈥渙kay, now I occasionally wear shorts like this.鈥� The nylon/spandex fabric lightly compresses upper leg and glute muscles while remaining extremely lightweight, and the multiple pockets give runners storage options. We liked the side pockets for carrying a phone or gels, the back pass-through pocket for holding things like gloves or even a long-sleeve layer, and the internal waistband pocket for stashing a key. The silicone grip dots on the leg hems keep the shorts in place and don鈥檛 leave a mark, and the 5-inch length strikes a good balance between coverage and freedom. 鈥淚 like that they are tights without being bun-huggers,鈥� said a tester.

Best Trail Shorts

Patagonia Endless Run Shorts 6鈥�

Sizes: XXS-XL

Pros and Cons
鈯� Material dries quickly
鈯� Three no-bounce pockets
鈯� Drawstring seems unnecessary

Many running brands are designing short tights right now, but the capabilities of the Patagonia Endless Run Shorts caught our attention. These shorts dried quickly from sweat, keeping us from getting hot when it was warm and from feeling cold and clammy even when the weather turned. The 6-inch length on a trail run provided coverage and protection from both the sun and overgrown trees on tight singletrack. The next-to-skin fit kept us covered while scrambling on rocks (no flashing trail partners), and the wide, flat waistband stayed put during fast efforts and long, rambling runs alike. The lack of a center seam kept these comfortable, even when doing high-knee warm-ups or during rock scrambles. One tester raved: 鈥淎 perfect length (not too short, but also not so long that they felt frumpy), perfect level of compression of the smooth, soft material that made me forget I had the shorts on.鈥�

Most Versatile

Tracksmith Session Shorts

Sizes: XS-XL

Pros and Cons
鈯� Casual styling
鈯� Performance functioning
鈯� Thin waistband isn鈥檛 flattering on all

The inseam length of these shorts may be a mere three inches, but the relaxed fit, subtle branding , and easy flow of the lightweight polyester/spandex shell fabric make these shorts versatile enough to run errands or grab a coffee (or beer) afterwards. The fabric raised suspicions at first, as it appears to be a soft knit that would hold sweat. But, as one tester put it, 鈥淭he fabric is a miracle鈥搃t dries quickly and just has a really nice drape to it.鈥�

The liner, made of Italian-sourced nylon/elastane, adds to the luxurious feel and functionality of the Session Shorts鈥攕oft against the skin, extremely lightweight, and quick drying. Three interior pockets in the liner add storage options to the one exterior zippered pocket, which holds items like AirPods rather awkwardly. Some testers found the thin waistband to be unflattering as it can create a 鈥渕uffin top鈥� around the midsection. Otherwise, we love how well these shorts perform on and off the trail.

Best Distance Training Shorts

Rabbit Fuel n鈥� Fly 4鈥�

Sizes: XS-XL

Pros and Cons
鈯� Plenty of pockets for storage
鈯� Comfortable, quick-drying brief
鈯� Can bunch up in the middle

The Fuel n鈥� Fly 4鈥� shorts have a whopping five storage options鈥攖wo back stash pockets, two internal stash pockets, and a zippered back pocket. What鈥檚 more, we noticed minimal movement even when stuffed with a small smartphone for a long run. One tester calls these her 鈥減ack mule鈥� shorts, adding, 鈥淣one of the pockets caused irritation or chafing when loaded,鈥� she said, adding that they didn鈥檛 budge or slide.

The back zipper pull tab is especially easy to grab while running. A lightweight polyester/spandex shell with perforations for added breathability feels 鈥渟oft and moves well,鈥� said a tester. The liner is notably quick-drying, which we loved鈥攊t鈥檚 not fun to run in a sweaty liner. The inner brief is also treated with an anti-odor peppermint oil that kept it smelling fresh.

Best 2 N 1

New Balance RC Short 2-in-1 3″

Sizes: XS-XL

Pros and Cons
鈯� Slightly compressive liner supports muscles
鈯� 2N1 design provides modesty
鈯� Liner material stays wet longer than some

We tested a host of shorts with an exterior shell covering an interior short tight, and these rose to the top. We liked the feel of the thicker-than-most seamless liner; its weight made it nicely compressive. One tester reached for these for light support of her high-hamstring strain. Testers praised the quality materials of both the liner and exterior shell, and the tailoring of the shorts overall. 鈥淚 really appreciate that they stay on my hips, where I put them,鈥� said a tester.

The exterior shell paired with the interior lining provided modesty for a range of activities without restricting movement. 鈥淵ou’re not flashing your neighbor when you鈥檙e doing burpees or planks, on treadmill runs, lifting workouts, or playing pickle ball,鈥� said a tester. Another enjoyed doing yard work after runs in these for the same non-neighbor-flashing reasons.

Two interior pockets and a back zippered pocket carried small items like AirPods or a key. Storing a phone in the back pocket, however, was too bouncy and awkward.

Best Short Shorts

Janji W’s 3″ AFO Middle Short

Sizes: XXS-XXXL

Pros and Cons
鈯� Light and airy
鈯� Comfortable waistband
鈯� 2-inch inseam on the frontside can feel bare

These lightweight, airy shorts with a 3-inch inseam are actually shorter than that鈥攖he backside extends to 3 inches while the front of the ultralight recycled polyester/elastane blend shell material is a mere 2 inches. One tester described the shorts as 鈥渂arely there fabric in a barely there fit.鈥� For some, these might feel too barely there, but for others, they are blissfully light and mobile.

The polyester/spandex brief liner is soft against the skin (but stays wet a tad longer than the shell). Our Virginia-based tester noted how well these shorts performed in hot, humid, dripping sweat conditions. 鈥淏ecause the outer is so fast drying, I would wear these shorts for SUPing as well. I just wish the liner dried faster,鈥� she said. Bonded seams and a knit waistband add to the overall comfort.

Most Comfortable

Oiselle Roga Shorts

Sizes: 2-24/26

Pros and Cons
鈯� Universally-flattering length
鈯� Comfortable, stretchy fabric
鈯� Tighter fit around the booty/thighs than other shorts

We love Oiselle鈥檚 original Roga Shorts for their wide, flat waistband that makes them sit as comfortably as yoga pants. The 4-inch inseam length and tapered sides are flattering, and the stretch woven polyester/spandex fabric is both substantial and lightweight. A semi-fitted cut provides coverage while the stretchy material moves with your body. 鈥淭hey sort of fit in between a short tight and a more traditional running short,鈥� said a tester, who described the material as having more structure than other shorts. 鈥淚 liked it鈥攊t wasn鈥檛 wimpy, but also not heavy or thick,鈥� she said.

Minimal seams in the crotch add to comfort, even during high-friction moves like high knees, and the shorts proved comfortable in hot and humid running conditions. 鈥淚 wore these for a treadmill run when I was super sweaty after sitting in a sauna, and they were great鈥攏o chafing,鈥� said a tester. Bonus: A tiny loop on the interior backside allows for easy hanging (to dry from all that sweat, for instance).

Best Shorts for Hot Temps

Bandit Vento 4″ W’s Training Short

Sizes: XS-XL

Pros and Cons
鈯� Flattering hem and overall style
鈯� Back yoke allows stashing a shirt/tank mid-run
鈯� Waistband elastic can feel a tad snug

The gathered waistband, perforations at the scalloped hem, and slightly shiny shell fabric of these shorts are as chic as Bandit鈥檚 home city (Brooklyn, New York). Testers commented that these look 鈥渦rban鈥� and 鈥渟tylish,鈥� but they also liked how they felt on the run. 鈥淰ery lightweight and breathable,鈥� said one. 鈥淎iry!鈥� said another. The material, a nylon/spandex blend with a slick finish, is treated for Durable Water Repellency, which keeps these from getting bogged down from sweat or a summer rainstorm.

Pass-through loops on the backside of the waistband allow easy stashing of a shirt or tank mid-run. And while three interior pockets on the liner are intended for gels, we found them mighty small and preferred nothing in them. 鈥淭hese feel more like a performance race short than a casual-jog short,鈥� said a tester.

What to Look For

When it comes to summer running clothes, look for breathability, moisture-wicking, and a chafe-free fit.

Materials

Sweat-wicking and quick-drying materials are essential. These are usually made of polyester or wool blends and have a wide variety of proprietary names and textures. Polyester weaves tend to be the most breathable and highly durable, while wool resists odors and has a natural feel next-to-skin. Try on as many options as you can to find the ones that are both soft against your skin and feel cool and airy.

Fit

The fabric should not restrict your movement or be so tight as to interfere with your breathing at all. When trying on garments, do some dynamic stretching such as leg swings, lunges, and running in place to experience your body鈥檚 whole range of motion in the apparel.

Shorts Style

Besides material and fit, there are a few key features to consider in running shorts: pockets, inseam, and waist height.

If you like to carry items like your phone, keys, sunscreen, water flask, gels, or snacks, you鈥檒l need more pockets (if you don鈥檛 run with a vest). Make sure the pockets are large and robust enough to fit and secure what you鈥檙e carrying, and located in spots where they won鈥檛 bounce or irritate. When you鈥檙e trying on shorts with pockets, test how they feel when the pockets are full鈥攅specially if you intend to carry something heavy like a cell phone, which can drastically change the way a pair of shorts fits and rides.

Consider whether you prefer shorts with a longer inseam鈥攍ike four to six inches鈥攆or more coverage and to avoid chafing, or ones with a shorter inseam that show a little more leg and feel less restricted.

The rise is crucial to consider, too. While some runners prefer a higher waist to feel more secure, others prefer a waistband that hits right at their hip bones and doesn鈥檛 constrict.

How We Test

• Number of testers: 8
• Number of products tested: 35
• Most extreme temperature experienced during a run: Sitting in a sauna then running on a treadmill; 95-degree Florida beach runs
• Most elevation gained during a run: 2,300 feet

The post The Best Women鈥檚 Running Shorts appeared first on 国产吃瓜黑料 Online.

It鈥檚 a Sunday morning and I鈥檝e just run 16 miles. I鈥檓 drenched in sweat, out of breath, thirsty, hungry, and exhausted. When I step through the front door, my husband calls 鈥渉ello!鈥� from upstairs, but otherwise no one else greets me. I stretch on the floor, cooling my muscles down before melting into the carpet face-down. Suddenly, I feel a lump step onto my back, and my cat, Steve, proceeds to perform some expert-level kneading into my muscles. He then curls up like the perfect heating pad and purrs himself to sleep.

And it鈥檚 glorious.

Growing up with dogs, I always assumed I鈥檇 have one when I was older. There鈥檚 no denying that they鈥檙e the perfect running buddies, unwaveringly loyal, and no one can resist a goofy puppy smile. But then I adopted my first cat, Ari, and the definition of my ideal pet changed. Today, I have three cats鈥攚hich is probably too many but if you like something you get one in every color, right?鈥攁nd though they can鈥檛 run with me, I wouldn鈥檛 trade them for the most athletic, well-behaved dog in the world.

To preface: I love both cats and . I鈥檇 even add a pup to the family one day if the time was right. But cats are misunderstood, underrated pets for runners. Before you boo and hiss, hear meow-t.

The Secret Life of Cats

My first cat Ari and I would occasionally take to the trails on a leash or in a cat-safe backpack. She鈥檚 a little older now and prefers a life of indoor lounging, but at our peak, we鈥檇 go to parks and she鈥檇 climb trees while I held onto her leash down below. You might be surprised to know that some cats lead active, outdoorsy lives鈥攁nd it鈥檚 a trend that鈥檚 gaining traction.

Eight years ago, Boulder-based influencer, filmmaker, and outdoorsman never anticipated that a cat could keep up with his on-the-go lifestyle, filled with hiking, climbing, swimming, backpacking, and trail running. But then Simon, now known as , was sort of thrust upon him. His landlord found a litter of stray kittens that needed rehoming, and Yosh felt compelled to take one.

鈥淚t was unplanned. I was traveling every weekend and not living a lifestyle that wasn鈥檛 even conducive for having a cat because I was going abroad a lot. The thought of getting a pet wasn鈥檛 even on my mind,鈥� he says. 鈥淲hen I got Simon, it was kind of like, 鈥業 want to make him an adventure cat鈥� because everyone in Colorado has their Subarus and takes their dogs on the trails鈥擨 can do it too.鈥�

Early on, Simon expressed the desire to be outside. But because Yosh lives in the backcountry, where it can be dangerous for cats to wander alone (coyotes, mountain lions, hawks, etc.) he started taking Simon out on supervised walks and hikes. Simon wears a harness and leash, but on longer hikes, likes to perch on Yosh鈥檚 back. And sometimes, these outings aren鈥檛 simple walks in the park. Yosh is an avid and has raced in ultras like the Collegiate Peaks Trail Run, Behind the Rocks Ultra, and the Run Rabbit Run.

Though Yosh doesn鈥檛 take Simon out on intense trail runs, when they鈥檙e out hiking together he can鈥檛 help dashing down ascents or running up hills, his cat either on his heels or his back. Together, they鈥檝e summited several Colorado 14ers (mountains with summits exceeding 14,000 feet in elevation), including Torrey鈥檚, Grey鈥檚, Massive, Elbert, and Quandary.

鈥淗e鈥檚 always strapped in securely on my back,鈥� Yosh says. 鈥淏ut he insists on exploring when we reach the summit鈥攊t鈥檚 like he knows he鈥檚 earned the view!鈥�

They鈥檝e even been camping in the snowy Indian Peaks Wilderness, which proved to be both challenging and rewarding with the amount of snow they had to trek through. 鈥淭he cold didn鈥檛 phase Simon, though鈥攈e snuggled up in his gear and enjoyed every second of the snowy adventure.鈥�

Yosh says that when he first got Simon, he rarely saw anyone outdoors with a cat. But over time, more and more felines are taking to the trails.

鈥淎t the time I never saw anyone with cats on the trails,鈥� he says. 鈥淏ut more and more people seem to take their cats out on adventures.鈥�

Take Sully, for instance, the 鈥渢rail running cat鈥�. The uber fluffy long-haired cat made waves when her owner, Katie Chen, posted a of them running along the trails together at an impressive pace. However, she鈥檚 clear on the fact that Sully is more of a sprinter than an endurance athlete, and doesn鈥檛 partake in long serious runs with her.

鈥淪ully and I start our day with a 20-30-minute morning leashed walk,鈥� Chen says. 鈥淚 enjoy a cup of coffee and let him explore around our home. Sometimes he stares at birds, sometimes he eats grass, and other times he gets a case of the zoomies. It鈥檚 very peaceful and nice to ease into my day in nature. It鈥檚 routine for him, so he expects it every morning!鈥�

With routine, practice, and lots of patience, your cats, too, can join you in your outdoor activities. If you鈥檇 like to start taking your cat outside, start by getting your feline acclimated to the harness and leash indoors. Yosh says that it took a lot of trial and error to find a harness that Simon liked, but says is his tried-and-true.

Have your cat wear the harness around the house for as much as they鈥檙e willing to until they get used to it. Then you can start taking them outside鈥攑referably at the same time and place.

鈥淎 routine is helpful, such as walks at a regular time each day,鈥� Chen says. 鈥淥nce you start this, your cat may be very vocal about going back outside. An established routine will help avoid this and keep everyone happy.鈥�

When you get your cat on the trail, just note that it鈥檚 going to be different than walking a dog.

鈥淐ats don鈥檛 like to be restrained, and you want to give them enough leeway so they never feel like they鈥檙e trapped,鈥� Yosh says. 鈥淵ou want to make sure the leash and harness move with the cat鈥檚 body. When I鈥檓 hiking with Simon, I always make sure I have a loose grip on the leash so he never feels constrained. Otherwise, your cat will resist you the entire time.

You鈥檒l have the most success if you allow your feline friend to take the lead.

鈥淵ou want to suggest things. You want to make cats think it鈥檚 their idea to go a certain way,鈥� Yosh says. 鈥淎nd cats are going to go at their own pace. They react to every noise, every butterfly and lizard.鈥�

He recommends that if you want to speed things up, you can use a pet-friendly backpack to carry your cat, or, as he does sometimes, have your cat rest across your back. That takes a lot of practice.

Ultimately, Chen and Yosh stress the importance of never forcing your cat into anything.

鈥淩unning around outdoors on a leash is not for every cat,鈥� Chen says. 鈥淵our cat may not like it, and you have to be okay with that conclusion.鈥�

An Argument for Cats, From The Mouth of a Runner

1. Cats sleep. All. The. Time.聽

My cats have improved my schedule, something everyone knows is essential to better recovery and running efficacy. Cats sleep about 12-20 hours a day. And even when they鈥檙e not sleeping, they enjoy mundane activities like looking out the window at birds, pacing the house, or batting around a toy mouse. My cats are usually conked out by 8 P.M., which honestly makes me a little sleepy, too. They encourage me to get to bed at a good hour.

Plus, cats make fantastic post-long run napping partners. Sometimes after I get home from an early morning workout, all I want to do is collapse on the floor and sleep. And your cat will absolutely join you, probably propping themselves right on your back and purring you into a lulled, wonderfully peaceful nap. They鈥檙e not interested in waking you up鈥攊n fact, they鈥檇 prefer if you just stayed right there all day and did nothing.

On the other side of the coin, cats will let you know when it鈥檚 time to start moving. They鈥檙e basically furry alarm clocks that wake you up early with pouncing and incessant meowing.聽

2. They鈥檙e the ultimate stretching partners.聽

Cats are stretching experts. And whenever I lay my mat on the floor, my cats are there to see to it that I get the work done. They are avid participants in my routine, but less intrusive than perhaps a dog might be (whenever I try to stretch around my brother鈥檚 golden retriever, she winds up barreling me over thinking I want to play鈥攕orry Ruth!). They merely lay contorted in similar positions as you, occasionally climbing up onto your back and leaping nimbly off when you move. Not only does it make the whole process more fun, but it tremendously, which is especially useful after a run.聽聽

3. They force you to slow down.聽

When I鈥檓 in a training block, I have a one-track mind. And sometimes, my obsession with splits and progress can take over until I inevitably hit a wall and burn myself out. But cats live life one paw at a time, with no agenda, schedule, or rush. I once watched my cat slowly stalk an ant for 15 straight minutes. Cats encourage you to take it easy, slow down, and examine your surroundings.

This applies to when you鈥檙e out on the trails together, too.

鈥淭he thing about dogs vs. cats is that dogs like to please their humans, whereas you need to please cats, so it鈥檚 a very different mindset,鈥� Yosh says. 鈥淭he whole time I have Simon, I鈥檓 taking care of him. With a cat, because you have to be so attentive to their needs, you become more mindful and respectful of what鈥檚 happening around you.鈥�

Yosh is so tuned-in to Simon that he can recognize a certain pitch in his meow that lets him know, if he鈥檚 on his back, that he needs to get down to go to the bathroom.聽

4. They offer just as much kinship as dogs.聽

I think one of most misunderstood preconceived notions about cats is that they鈥檙e cold, disinterested, and unloving. Cats can definitely provide affection, loyalty, and support. shows they recognize behavioral shifts and mood changes, which is why my cats seem to flock to my lap when I鈥檓 stressed about a quick deadline or sit protectively at my feet if I鈥檓 sick in bed.

鈥淪imon definitely provides an extreme amount of emotional support,鈥� Yosh says. 鈥淚f I鈥檓 in a stressed mood, he鈥檒l come over to me and demand I pet him as a way to take focus on whatever is stressing me out. It鈥檚 sort of a reminder like, 鈥楬ey life might be hard, but you have me.鈥� That reassurance is so comforting.鈥�

The post Why Cats Make the Purr-fect Companions for Runners appeared first on 国产吃瓜黑料 Online.

Remaining Native begins with a warning: This is a film that doesn’t shy away from abuse, violence, or any of the other crimes that darken Native American history. But that’s also the film’s strength: The feature-length documentary captures what it means to be a , balancing joys and tragedies in a way that will resonate with any athlete鈥攁nd any human being.

Remaining Native, which will be screening alongside a curated lineup of other top adventure films at this year’s 国产吃瓜黑料 Festival, is a beautiful, powerful, and important documentary by filmmaker Paige Bethmann, a Haudenosaunee (Mohawk/Oneida) woman. Bethmann鈥檚 great grandmother was stolen from her reservation as a girl and taken to an abusive Catholic boarding school. Tragically, Bethmann鈥檚 ancestral story is common to hundreds of thousands of Native Americans, including the subject of Remaining Native, Kutoven (鈥淜u鈥�) Stevens.

The film鈥檚 opening lines explain:

For over 100 years, the United States made violent efforts to strip Native American children of their languages, spiritual beliefs, and culture through federal and church-run boarding schools.

Many children resisted this assault on their Native identity by running away.

From this prelude, the viewer knows to take a deep breath and buckle up. But then, beauty: scenic shots of the desert landscape. A hawk high in a tree. The rhythmic sound of a runner鈥檚 footfall on an open dirt road. And we鈥檙e introduced to the boyish face and voice of the film鈥檚 hero, Ku Stevens.

Ku is a runner鈥攐ne of the best in the state of Nevada, having clocked the fastest time across all divisions in the high school state cross country championships. Through interviews, voiceovers, and scenes of Ku living with his parents on the Paiute Indian Reservation in the small town of Yerington, we get to know the teenager. We learn that he鈥檚 always wanted to run for the University of Oregon and pushes himself to be the best he can be.

Like most runners, he says that when he runs, he thinks about his breathing and his body. But, he adds, he also imagines running for his life.

Stevens’s great-grandfather ran away from the Stewart Indian Boarding School three times. His last attempt was a successful escape. That legacy is often on Stevens’s mind.

The film does a fantastic job of weaving together inspiring action scenes that any sports fan can appreciate with sepia-toned historical images set to haunting tribal music.

鈥淭his land I was raised on, it feels heavy,鈥� says Stevens. Through shots of barren landscape and close-up faces of those who live here, we feel it.

Parents of teens will appreciate the internal struggle of Stevens’s father, who loves and supports his son, but fears he鈥檒l lose his ancestral heritage by moving off the reservation. Still, he and his wife do everything they can to help the young runner reach his goals.

One of the most exhilarating scenes of Remaining Native takes place at a high school track meet, where Stevens attempts to run the 3200-meter under nine minutes鈥攁 benchmark that’s become the recruiting standard for distance athletes hoping to run for the University of Oregon. The racing drama is on-par with any Olympic final or Disney sports movie.

Among the most poignant moments of Remaining Native鈥攁nd there are many鈥攃omes with a slow pan of a black-and-white image from the Stewart Indian School. Native American children sit with pained faces, hair cut short, sadness in their eyes. A drumbeat plays, as if to hammer into our awareness that this bit of American history, when thousands of Native American children were stolen from their families and died or survived abuse, happened. It actually happened. And yet, people like Ku and his family keep fighting for their culture while trying to heal from their past.

At one point in the film, Stevens says, 鈥淚 really just want people to understand鈥攏ot just to know what happened, not just to learn from our history鈥攂ut to fully understand why we feel the way that we do.鈥�

At one point in the film, the teen explains that his name, 鈥淜utoven,鈥� refers to 鈥渢he eagle bringing the light from the darkness鈥� and that he doesn鈥檛 yet feel he lives up to its meaning. Viewers of Remaining Native will beg to differ.

The post 鈥淩emaining Native” is for Runners鈥攁nd for all Human Beings appeared first on 国产吃瓜黑料 Online.

None of Marcus Samuelsson鈥檚 childhood memories took place inside. Growing up in Gothenberg, Sweden, the acclaimed chef, who was born in Ethiopia, spent much of his time on the water fishing or in the forests foraging for mushrooms or lingonberries. His uncles, professional fishermen, would take him with them for their daily catch. Surrounded by a vibrant food culture, Samuelsson apprenticed in kitchens in Switzerland, Austria, and France before moving to New York City in the 1990s. He channeled his love of soccer into long runs through Central Park and beyond, exploring the culinary mecca mostly on foot. He ran and in-line skated his way through Manhattan, first as an apprentice at Aquavit, a Scandinavian restaurant in Midtown, and then as its executive chef. There, Samuelsson became the youngest chef to earn a three-star rating from The New York Times. Samuelsson, now 54, still runs through the city, often dreaming up dishes for his new restaurant, Marcus Addis, in Addis Ababa, Ethiopia.

OUTSIDE: I hear you have a rule: no matter where you are in the world, you exercise four times a week. Often you run. How does a kid from Gothenburg become a lifelong runner?

I think it鈥檚 because I鈥檓 Ethiopian. I grew up watching sports, and . Like them, I found it easy to run. It was something in my veins that I enjoyed, and I鈥檓 light on my feet. I played a lot of soccer as a kid too, but as I grew up and started working in kitchens鈥攈aving less time for team sports鈥擨 started running just to run. Running gives you freedom. You start to think about your outside experience differently than when you鈥檙e playing on a team with a coach, refs, and so many moving parts. It was like skateboarding or biking as a kid鈥攁 sense of freedom and discovery that I really enjoyed.

How did running shape your relationship with New York City?

It became my way to explore. I like to , especially in the early morning, when there aren鈥檛 that many cars. There is a sense of discovery that you can鈥檛 get once a city is fully awake.

But one of my favorite ways to see the city was on Rollerblades. I鈥檇 skate from Midtown down to Chinatown to discover the best food stands, or find places where you can pick up international foods like galangal or different types of ginger that weren鈥檛 [available] in Midtown. The train or a cab was out of my budget, so Rollerblading or running became the ways I got down there.

What makes running in Central Park one of the best places in the world?

If you go for a run in Central Park on a weekend, you meet people from all over the world doing something鈥攎aking music, praying, screaming. Whatever it is, they鈥檙e doing it well. You run past iconic places, like where John Lennon lived. If you run downtown, you see beautiful historic buildings鈥攊t鈥檚 urbanism at its fullest.

How did you decide to run your first marathon? What did your training plan look like?

It was a challenge from my mom. Growing up, she pushed me constantly. She challenged me to open a restaurant in Harlem [Red Rooster, in 2010], and we were arguing about whether I was still an athlete. I鈥檝e always been naturally athletic鈥擨 could roll out of bed and play sports pretty well. But she said, 鈥淵ou鈥檙e not an athlete anymore.鈥� To prove her wrong, I ran my first in 2001鈥攚ithout any proper marathon training. I was only running maybe six miles at a time, and I never built up to twelve or eighteen miles. I paid dearly for it. I don鈥檛 recommend that to anybody.

You鈥檝e gotten involved with run clubs recently. How does running with other people change the experience for you?

I love running with young people. You get into new music, learn new slang and trends鈥攖hat鈥檚 exciting to me. It鈥檚 fun to share space with people who aren鈥檛 part of the chef community. I love that. And people [I meet at run clubs] are always excited to learn I鈥檓 Ethiopian鈥攂ut I鈥檓 probably the slowest Ethiopian you鈥檒l ever meet. I blame it on being Swedish.

Has running altered your relationship with food?

You know, it鈥檚 not just running鈥攊t鈥檚 spending time outdoors with my kids. When fall comes around and it鈥檚 time to pick apples or pumpkins, that鈥檚 such a great way to be outside with the family. Not only does it take them away from their iPads, but it鈥檚 also the kind of food-driven freedom I grew up with. I realized that Swedish freedom is a luxury, and I鈥檓 trying to give my kids that same sense of luxury.

Running is also a good time to meditate on my work. I鈥檇 come to understand umami while running鈥攖hinking about how I can improve my processes and recipes. A lot of that happens during the cerebral thinking process when you鈥檙e running.

Has running ever inspired a dish? Can you share one you came up with while on a run?

At Hav & Mar [his seafood restaurant in Chelsea], we have a dish called Addis York, which really balances New York City life with Addis Ababa. That鈥檚 not a dish I would have come up with in a kitchen. It popped into my head on a run, where I get space from the kitchen and have time to think deeply. I was wondering how to connect these two places and came up with the idea of placing a piece of Ethiopian-spiced fried chicken on top of injera with doro wot stew.

Do you find that running helps you find some zen?

When I travel for work, running takes over my thoughts. Right now, I鈥檓 in Miami for an event, and all I can think about is . Running is decompression time. A lot of people focus on the distance when they run, like it鈥檚 work. For me, it鈥檚 more about the excitement of looking at the ocean or exploring the city.

Why was it important to you to open your restaurant in Addis Ababa?

I have a very strong heritage there: my half-siblings from my father鈥檚 side, my wife鈥檚 brother, and her mom all live there. We travel to Ethiopia often. I鈥檓 really excited about the restaurant because it鈥檚 connected to a school where Ethiopian students have a path to study hospitality, learn to problem-solve, and work together. It gives them a path to a job and a path to success. That makes me really happy.

Why is your work with World Central Kitchen so meaningful to you?

During the pandemic, Jos茅 Andr茅s and World Central Kitchen were among the first people to come to Harlem when we truly, truly needed help. With their support at Red Rooster, we served more than 1,000 people per day for several months.

We recently went to Altadena, California, to help after the fire, and the devastation was shocking. But it also brought out the best in people. In the worst of times, you see real people鈥擜mericans helping Americans. No one cares who鈥檚 a Republican or a Democrat. That makes me proud of the organization and proud to be an American, especially when that can feel challenging.

Summer running is difficult enough with the challenges of heat and humidity. The last thing you need is to be held back by running shorts that bunch, cling, chafe, or restrict your movement. The perfect running shorts should be so comfortable that you hardly notice them, while looking so good that others do. We tested over 40 pairs in the most sweltering conditions to find the best running shorts for you, whatever your style.

While you鈥檙e at it, be sure to check out our picks for the best running shirts for men and the best running shoes.

Updated April 2025: We鈥檝e removed three shorts and added six new picks from Rabbit, Outdoor Research, Terignota, Black Diamond, Ciele, and Ten Thousand.

Best Overall

Rabbit Fuel n’ Fly 5″

Sizing: S-XL

Pros and Cons
鈯� Comfortable and supportive brief liner
鈯� Excellent mobility and ventilation
鈯� Secure and comfortable waistband
鈯� Limited colors
鈯� Pocket is a tight fit for larger phones

Our testers across the board raved about the Rabbit Fuel n’ Fly 5鈥� shorts. 鈥淓very little detail feels thoughtful and perfect,鈥� said one. The outer shell, made from a recycled polyester and spandex blend, strikes a balance between lightweight comfort and long-lasting durability. Inside, the Polartec Power Dry liner was among the most comfortable, moisture-wicking, and supportive we tried. One tester who typically wears underwear with running shorts for added support said these provided plenty on their own.

The semi-relaxed fit with half-split leg design, usually seen in 3-inch racing shorts, enhances both mobility and ventilation. 鈥淚 dig the fit and the cut, which is roomy without being baggy,鈥� one tester commented. Thoughtful touches like bonded hems, anti-odor liner treatment, and laser-cut square perforations along the front sides elevate the short鈥檚 overall feel and performance.

The drawstring waistband is wide yet not constricting, offering a secure anchor when loading the shorts鈥� five pockets: a zippered back pocket, two front internal stash pockets, and two rear stash pockets. The rear pocket can hold an iPhone 14, but it requires a bit of effort to get it in. The only other downside is the lack of color choices: it comes only in a standard black and seasonal blue.

Runner Up, Best Overall

Outdoor Research Swift Lite Shorts

Sizing: S-XXXL

Pros and Cons
鈯� Comfortable, flowy shell fabric
鈯� UPF 30 sun protection
鈯� Dries quickly, doesn鈥檛 cling when wet
鈯� Limited storage

As a recognizable outdoor gear brand, Outdoor Research might not be the first brand that comes to mind for running apparel, but the Swift Lite Shorts left a strong impression on our entire testing team. Crafted with a polyester and spandex blend, the shell fabric felt comfortable and flowy against the skin, causing one tester to call it his 鈥済o-to, pull-on-and-forget-it option, especially for trail running.鈥� The gusseted crotch and lightweight fabric with just the right amount of stretch allowed full freedom of movement without riding up, along with excellent moisture management. 鈥淭he fabric dries quickly and stands away from the skin, never getting clingy or soaked,鈥� noted one tester, qualities that he said made it a standout for sweaty, warm-weather efforts. As an added bonus, the shell carries a rare UPF 30 sun protection rating.

The internal polyester brief liner provides solid support, while the jacquard waistband with an external drawcord keeps the shorts securely in place without feeling tight or restrictive. Thoughtful details, such as notched sides, a laser-cut hem, and ventilation holes increased comfort and style points. The standard 5鈥� inseam and classic fit strikes an ideal middle ground between too baggy and too revealing. One tester remarked, 鈥淭hanks to a light stretch and strategic tailoring, it looks good enough to continue wearing casually post-run.鈥�

Our only gripe is the limited storage: the single rear zip pocket didn鈥檛 offer enough space for essentials and wasn鈥檛 large enough to fit a phone. That said, if you can get by without extra pocket space, you鈥檒l be treated to a comfortable, durable, great-looking pair of running shorts that never draw attention to themselves on the run.

Best Value

Terignota Sendero Short

Sizing: XS-XL

Pros and Cons
鈯� Lightweight, airy shell
鈯� Abundant storage options
鈯� Exceptional value
鈯� Limited colors
鈯� High-rise waistband may feel awkward at first

With all the features of shorts costing twice as much, the Terignota Sendero Short proves that high performance and sharp design don鈥檛 have to break the bank. Its polyamide and elastane grid-patterned outer shell is remarkably lightweight and airy. The no-fuss internal mesh brief liner offers a good amount of support without feeling restrictive. One tester gave the short the highest praise: 鈥淚t鈥檚 one of those shorts that disappears on the run.鈥�

The Sendero鈥檚 highlight is no doubt its carrying capacity. Built with trail runners in mind, the wide waistband includes four mesh pockets and a rear zippered pocket spacious enough to fit an iPhone 15. One tester noted that the high-rise fit of the waistband鈥攗nusual on a men鈥檚 short鈥攆elt a bit awkward at first, but he quickly became accustomed to it after a few runs. Even with the wide waistband, however, when the pockets were fully loaded, we had to cinch the drawstring tightly to keep everything secure and minimize bounce.

Best Run/Gym Hybrid Short

Ten Thousand Session Short

Sizing: XS-XXL

Pros and Cons
鈯� Durable, robust shell
鈯� Comfortable and secure waistband
鈯� Options on inseam length and brief style available
鈯� Limited breathability
鈯� Bouncy pockets when loaded

Most running shorts scream 鈥渞unner鈥� with their short inseams, ultralight fabrics, and performance-first design at the expense of everyday style. The Ten Thousand Session Short 2.0 flips that script, delivering a gym short鈥檚 clean, modern look without compromising the technical functionality of a high-performance running short.

Available with either five- or seven-inch inseams, and with your choice of a 2-in-1 liner or linerless, the Session Short 2.0 is built from a substantial polyester and spandex blend that feels noticeably more robust than typical run-specific options. While they don鈥檛 breathe quite as well as lighter shorts, a California tester said, 鈥淚 never found them too heavy for runs, and that extra heft gives them a more versatile, gym-ready vibe.鈥�

The perforated waistband, with a thick internal drawstring, stayed put during runs and felt comfortable even when tightly tied. Two zippered side pockets鈥攐ne facing forward and the other smaller and facing backward鈥攍et heavier items bounce around when running, but held cards and cash securely and comfortably in the gym. Two internal drop-in stash pockets in the liner provide space for items like keys and a phone when working out in the gym, but proved less than ideal for running because of the lack of a secure top closure.

What truly sets the Session Short 2.0 apart is its versatility. With a sleek, structured look and a robust fabric, these shorts easily transition from a hard effort on the track to a coffee stop or casual meetup without screaming 鈥淚 just ran.鈥�

Best for Race Day

Hoka Glide 5鈥� Short w/ Brief

Sizing: XS-XXL

Pros and Cons
鈯� Extremely lightweight
鈯� Thin but supportive liner
鈯� Phone bounces in back mesh pocket

When you need lightweight freedom and zero distractions on race day, the Hoka Glide 5鈥� Short delivers seamless comfort and dependable support that lets you focus on one thing鈥攔unning your fastest. The shell is crafted from a featherlight, stretch-woven polyester/spandex fabric with a DWR finish, while the thin mesh liner offered a surprising amount of support and breathability. 鈥淭he fabric is super lightweight and ultra stretchy, plus the fit is roomy enough that these barely feel like wearing anything,鈥� said one tester. One tester pointed out that are a more modest alternative to one-inch split shorts for race day, while still allowing unrestricted freedom for your longest strides.

Thanks to the minimal design, these shorts stood out during hot and humid summer runs. One tester reported, 鈥淓ven on my sweatiest days, when I was drenched, the shorts stayed soft, comfortable, and unrestricted.鈥�

The shorts feature a small zippered pocket ideal for securing essentials like keys and money, and a spacious mesh rear pouch, open on both ends and large enough to hold a phone or soft flask. While large items in the mesh pocket bounced around a bit during runs, this isn鈥檛 an issue if you鈥檙e not carrying a phone on race day.

Best Splurge

Soar Run Shorts

Sizing: XS-XXL

Pros and Cons
鈯� Good blend of comfort and performance
鈯� Suitable for most seasons
鈯� Pocket is too small for a phone

Based in the UK, Soar running makes some of the highest quality, best-looking running apparel we鈥檝e tested. Combining striking design with exceptionally fast-drying fabric and luxury features like laser-cut ventilation holes and bonded hems, these shorts became our go-to choice whenever we wanted both standout style and top-notch performance.

The 5鈥� inseam strikes a balance between modesty and uninhibited motion. Notched side hems and a stretch woven fabric bolsters mobility while a comfortable polyester and elastane brief liner provided excellent support. The slim drawstring waistband remains comfortable and never squeezes. These shorts truly disappear during the run.

The only thing we鈥檇 knock them for is lack of storage. With a single rear zippered pocket that鈥檚 too small for a phone, we found it hard to carry fuel on long runs. That said, we鈥檝e tested these shorts for two years now, and they have held up remarkably well.

Best for Trail Running

Black Diamond Distance Short

Sizing: XS-3XL

Pros and Cons
鈯� Outstanding pockets
鈯� Water- and wind-resistant shell
鈯� Available in 5鈥� and 7鈥� inseam
鈯� Short drawstring can be difficult to tie
鈯� Could use a little more stretch

鈥淭he Black Diamond Distance shorts get everything right,鈥� one tester remarked. The pockets are the first thing that stood out. With four drop-in pockets and one large rear zippered pocket, these shorts impressed us with their copious, efficient carrying capacity while maintaining a comfortable fit suitable for the longest mountain days. We were able to easily carry an iPhone, enough fuel for a few hours, and an emergency shell without any discomfort.

Offered in five- and seven-inch inseams, the durable shell with a PFC-Free DWR sheds light moisture and resists snags and tears from bushwhacking and tumbles. Combined with a comfortable and supportive mesh brief liner, the tough exterior offered excellent protection against wet, chilly ridge winds when running in the high mountains.

One small quibble: a tester said he鈥檇 prefer a longer drawstring with a little bit of stretch to get a more secure fit around the waist when the pockets were loaded down.

Best 2-in-1

Ciele M DLYShort 5″ Long Brief

Sizing: XS-XXL

Pros and Cons
鈯� Incredibly soft and supportive liner
鈯� Available in long or short liner
鈯� Phone bounces in pocket

Ciele is best known for its performance running hats, but the brand nailed it with the DLYShort 5″. 鈥淭hese shorts feel deluxe!鈥� raved one tester.

The internal nylon and elastane liner is one of the softest and most comfortable we tested, offering excellent support and staying perfectly in place throughout the run. Even when drenched in sweat, it remained irritation-free. The shell is a lightweight, stretchy, recycled, woven fabric with a PFC-free DWR treatment. However, it feels much softer than other DWR-treated fabrics we tested. One tester called the short鈥檚 overall feel 鈥渙ut-of-this-world nice,鈥� while another praised its classy looks: 鈥淚鈥檝e gotten more compliments on group runs for these shorts than anything else in my running wardrobe.鈥�

The shorts offer three pockets, a rear zipper, a small internal stash pocket, and one integrated into the liner. While we could fit a phone in the rear pocket, it unfortunately bounced around quite a bit, and we found it best to reserve the pockets for smaller, lightweight items.

If you’re a fan of 2-in-1 shorts, these are well worth the investment. And if you鈥檙e not a fan of the long liner that extends past the 5-inch inseam of the shell, Ciele offers an option with a shorter one.

Best Half Tights

Adidas Adizero Control Running Short Leggings

Sizing: XS-2XL

Pros and Cons
鈯� Supportive fit
鈯� High-quality material
鈯� Thick fabric can run hot

There鈥檚 something uniquely satisfying about the feel of snug, supportive tights hugging your muscles. The Adidas Adizero Control Running Short Leggings, crafted from a relatively thick blend of 83 percent polyester and 17 percent elastane, delivers mild compression to your quads, glutes, and hamstrings, ensuring they stay engaged and protected during even the most intense runs.

Flexible, rubber-like (TPE) strips stretch across the major muscles to add additional support. The result is a tighter, more supportive fit than the other tights in this test. However, although you might expect them to feel restrictive, the material is surprisingly stretchy and flexible, allowing full range of motion. The downside is that they can feel too warm in hot conditions. But that聽was one of our few complaints about these tights that otherwise made us feel fast and powerful.

What to Look For in Running Shorts

Running shorts vary in length, liners, pockets, fit, and fabric. You鈥檒l want a length that is short enough for full, unimpeded motion (the faster the run, the shorter and more split the shorts tend to be), but long enough to feel decent on the trail, road, or post-run coffee shop.

Liners range from soft, loose briefs to compression-shorts-like stretchy boxers鈥攐r none at all for those who prefer to wear their own underwear. Choosing between liners is a matter of personal taste, balancing breathability and range of motion with level of coverage and control.

Pockets need to be big and secure enough for whatever you want to carry: phone, keys, cards, gels. And pocket placement location is important to allow convenient access and avoid bouncing and chafing, as is the robustness of the waistband to prevent sagging when carrying anything heavy, like a phone.

When it comes to fit and fabric, as with all summer running gear, you want pieces that breathe, wick moisture, move naturally, delay stink, and don鈥檛 get in the way.

Here are some quick tips on buying the best summer gear without going broke:

• Look for high-quality synthetic fibers. Yes, our top picks include a few items with natural fibers. But for the most part, specially designed varieties of polyester, polyamide, nylon, and the like can handle summer running鈥檚 high sweat rates better than wool and cotton.
• Seek sun protection. Even if you run at dawn or dusk, or on shaded trails, sun damage can be insidious. Many shorts and tops come with a UPF coating. Running tan lines aren鈥檛 something to be proud of.
• Check for chafing. If you鈥檝e ever been rubbed raw by a rigid seam or sagging liner, you won鈥檛 want to repeat the experience. Abrasion accelerates when you鈥檙e drenched in sweat. Look for flat seams, unobtrusive logos, and other elements of construction that will minimize chafing.
• Go with the flow. Our picks in this review strike the right balance between being loose enough to allow cooling air flow but not so billowy that they impede normal running form.
• Banish bacteria. Many summer running items incorporate an anti-bacterial treatment that greatly reduces nasty odors setting up shop. These pieces not only can be worn many more times before needing to be washed, but also lessen your chance of developing a funky skin situation.
• Invest in quality. It can be tempting to think, 鈥淲hatever I run in is going to get soaked anyway, so I鈥檒l just buy the cheapest gear out there.鈥� Such reasoning quickly falls apart when, well, the item itself starts to fall apart because of constant exposure to sweat and frequent laundering. Fewer high-quality pieces that hold their form and don鈥檛 hold odors are better than more cheaply made gear that will start disintegrating in one summer.

How We Test

• Number of testers: 10
• Number of shorts tested: 40+
• Number of miles run in testing: 4,500+
• Highest testing temperature: 97 Fahrenheit

Our testing team ranged across the U.S.鈥攆rom coastal Maine and western Maryland to central Wisconsin, the high plains of Nebraska, the urban bake sites of Chicago and Houston, and out to Santa Barbara on the California coast, plus, for good measure, the running hub of Eugene, Oregon. All are dedicated runners with average weekly mileage ranging from low 20s to mid 70s. Some have been running for 30 or more years and can compare today鈥檚 running apparel to previous attempts to keep runners cool in the summer.

We focused on a subjective combination of moisture management, comfort, versatility, value, and looks to answer a simple question: Of all the apparel you logged summer miles in, which would you be most likely to recommend to fellow runners?

The sun is shining, the birds are chirping. Summer鈥檚 longer days and warmer temperatures make for fun and free running. There鈥檚 just one problem: The heat can sap your running performance and enjoyment. Choosing the right apparel in summer鈥攊n the same way you bundle up in winter鈥攃an make the conditions not only bearable, but fun.

In this season, we need running shirts that slip on effortlessly when we鈥檙e still half-asleep in the morning, and float on our skin when we鈥檙e cramming in a tempo workout on a sticky afternoon. We searched for, and found, the best women鈥檚 running tops鈥攖-shirts and tanks鈥攖hat can handle the challenges of summer while making us look good and feel cool.

Update May 2025: We selected new running tops in all but one category, carrying over the perennially popular Tracksmith Session Tee. We also added objective lab measurements on air permeability and dry time to help you select the best summer running shirt for you. Be sure to check out the 鈥淗ow We Test鈥� section below for more details on our methodologies and how to interpret the lab data.

Best T-Shirt for Hot Weather

Craft Pro Hypervent Running Tee 2.0

Sizes: XS-XL

Pros and Cons
鈯� Extremely lightweight
鈯� Seamless comfort
鈯� Shows sweat

Lab Dry Time: 3 (1=worst; 5=best)
Lab Air Permeability: 3 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

In summer heat, a shirt that feels barely there and still provides shoulder coverage is a Godsend, and the Craft Hypervent Tee 2.0 delivers. It鈥檚 made of a super-lightweight recycled polyester/elastane blend that isn鈥檛 the fastest drying or airiest but is silky smooth against the skin with a mesh back that breathes well while still shielding us from the sun. 鈥淚t鈥檚 great for summer heat because it鈥檚 so lightweight鈥攊t flitters like an aspen leaf,鈥� raved a tester.

Taped seams at the neck and sleeves are comfortable (no chafing) and add to the shirt鈥檚 feminine silhouette. The sleeves are cut longer than regular tees and add coverage, while the raglan design allows unrestricted arm movement. 鈥淣o seams is a huge plus for me,鈥� said a tester who also loved the lack of a papery tag rubbing the back of her neck. 鈥淭his was a shirt I didn’t have to think about while running,鈥� said another.

Best Tank for Hot Weather

Patagonia Capilene Cool Daily Tank

Sizes: XS-XL

Pros and Cons
鈯� Extremely lightweight
鈯� Minimal branding allows versatility
鈯� Runs large

Lab Dry Time: 4 (1=worst; 5=best)
Lab Air Permeability: 3 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

We loved the feel of this tank for everything from warm-weather runs in Colorado to high-humidity hikes in the Caribbean. Testers described the recycled polyester Capilene Cool fabric as 鈥渆xtremely lightweight鈥� and said it helped them 鈥渕aintain comfort while sweating.鈥� The thin fabric dries quickly, a bonus in summer heat, whether on the run, during water sports like stand-up paddleboarding, or when traveling.

Like most Patagonia apparel, the fit of this tank runs a little large, but we liked the relaxed shape. It鈥檚 one tester鈥檚 go-to shirt while wearing compression-style bootie shorts. 鈥淚 like the coverage of the longer cut,鈥� she said. We also loved the versatility of the tank鈥檚 styling鈥攖he only visible branding is a tiny Patagonia tag at the bottom seam, so it doesn鈥檛 look overly athletic and out of place off the trail.

Best Raceday Tank

Hoka Airolite Run Tank

Sizes: XS-XXL

Pros and Cons
鈯� Airy fabric and cut
鈯� Fabric is rated 40+ UPF
鈯� Higher neckline provides coverage
鈯� Can creep up under a pack

Lab Dry Time: 2 (1=worst; 5=best)
Lab Air Permeability: 5 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

This tank is ready for race day with a highly breathable material and a slim fit that stays out of the way of an arm swing. We love the airy feel of the super lightweight pinhole mesh combined with an even-more-open mesh panel on the upper back鈥搕he whole tank breathes fantastically. It鈥檚 thin, super lightweight, and feels cool against the skin. 鈥淚 definitely noticed it helped keep me feeling cooler and dry even when sweating heavily in higher temps,鈥� said a tester. 鈥淚t feels very performance-oriented,鈥� said another. In the lab, it scored the highest mark for air permeability among all shirts tested. The fabric is so light that it crept up a bit while we tested it under a hydration vest, but it stays perfectly put on its own.

Most Versatile Tank

Brooks Luxe Tank

Sizes: XS-XXL

Pros and Cons
鈯� Super soft
鈯� Minimal branding
鈯� Underarm seams slightly rub (but not chafe)

Lab Dry Time: 3 (1=worst; 5=best)
Lab Air Permeability: 2 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

This soft, breathable, minimally branded tank looks so good we鈥檝e worn it casually to run errands around town, but the stylishness doesn鈥檛 compromise how well it feels and moves on the run. The cut is slightly long and loose, which makes it comfortable, flattering, and adds to its versatile appeal鈥攊t can work both tucked in or left out. 鈥淪o soft and breathable,鈥� said a tester, while another marveled at how lightweight the material felt against her skin.

A couple testers noted the underarm cut was a tad high, making the non-flat seams rub their armpits, but it was more of an irritation than a run-ruining situation鈥攏o chafing. But that was easy to overlook given the tank鈥檚 versatility. 鈥淭his tank is great to layer under a long sleeve for a morning run when it starts cool and will warm up,鈥� said one tester. 鈥淚 also love it for a short run, when it can double as a casual tank to run errands in before or after.鈥�

Most Versatile Tee

Tracksmith Session Tee

Sizes: XS-XL

Pros and Cons
鈯� Versatile
鈯� Soft and Stretchy
鈯� Runs slightly large

Lab Dry Time: 1 (1=worst; 5=best)
Lab Air Permeability: 2 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

We鈥檝e used this as a go-to running tee and an all-day tee鈥攚earing it casually throughout the day then on an evening run. One tester even slept in it. Made of 84 percent polyester and 16 percent spandex, the Session Tee is exceptionally stretchy. It鈥檚 also finished with an odor-resistant treatment that seems to work: We鈥檝e worn it for multiple runs without washing and swear that we鈥檙e not offending trail partners. (They concur.) The Session Tee dries slower and is less airy than other high-performance tops鈥攕o it isn鈥檛 the best choice for the hottest days鈥攂ut makes up for that in soft comfort and style.

鈥淚鈥檓 in love with everything about this shirt: the fit, the fabric, the performance,鈥� said a tester. 鈥淚t felt like a hang out shirt that I could run in!鈥� another raved, 鈥淚 forgot about this shirt during the run because it was so comfy and has the most perfect fit!鈥�

Best Value

2XU Aero Singlet

Sizes: XXS-XL

Pros and Cons
鈯� Lightweight and breathable
鈯� Reflective detailing
鈯� Can feel loose around the midsection (this can also be a positive)

Lab Dry Time: 5 (1=worst; 5=best)
Lab Air Permeability: 3 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

It鈥檚 hard to find well-functioning running apparel under 40 bucks, but this tank delivers. Its lightweight, sweat-wicking front (a double-knit recycled polyester), combined with a super-breathable mesh back kept us cool for all our summer running. 鈥淭his tank wicked sweat away, didn鈥檛 chafe, and was very comfortable in warmer temps,鈥� said a tester.

The simple cut provides a bit more coverage on the backside than traditional racerback tanks, and has a looser fit around the middle. Some felt it to be too baggy at the waist and loose on the lower back while others liked the flowy feel. Reflective details add safety in dusk and dawn light.

鈥淭he lightweight fabric throughout seems inherently breathable,鈥� said one who also praised how quickly sweat dried. 鈥淭he fabric is slightly textured as opposed to just one single layer which seemed to encourage even more airflow, and it dried quickly,鈥� said another. The lab confirmed the testers observations: this tank had the best combined performance scores of all the tops we tested.

Best Trail Running Tank

Arc鈥檛eryx Norvan Tank

Sizes: XXS-XXL

Pros and Cons
鈯� Wide shoulder straps work well under a pack
鈯� Lightweight, airy, and quick-drying
鈯� 80 bucks is a lot for a tank

Lab Dry Time: 5 (1=worst; 5=best)
Lab Air Permeability: 2.5 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

Some tank shoulder straps can start to rub underneath a hydration vest or traditional running pack straps, but not the straps on this one. A wider cut at the shoulders stayed flat and in place under a pack during hours of mountain running in Colorado鈥檚 Indian Peak Wilderness.

This is a looser-fitting tank, which we loved for its forgiving fit all around and slightly longer cut. The material鈥攁 softer polyester frontside with a meshy backside鈥攆eels great against the skin, breathes well, and dries quickly (the fastest-drying of all the tops here, according to the lab). All seams remained comfortable over hours of wear as well鈥攏o chafing here.

Best Trail Running Tee

Black Diamond Distance SS Tech Tee

Sizes: XS-XL

Pros and Cons
鈯� Extremely lightweight, breathable, and quick drying
鈯� Zero irritation over long wear
鈯� Not as cottony feeling as some others

Lab Dry Time: 4 (1=worst; 5=best)
Lab Air Permeability: 3 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

We鈥檝e worn this tee under a pack over multi-day runs from hut to hut in the White Mountains of New Hampshire, as well as on multiple short runs around the Boulder Foothills and neighborhood suburbs. This shirt performs: It鈥檚 super-quick-drying, moisture-wicking, highly breathable polyester jersey material with a 鈥淨uick Dry鈥� finish that never feels bogged down with sweat. The Anti-Odor finish also proved effective鈥攄id we mention that multi-day, multi-wear hut trip? We got no complaints from our running mates. Flat lock seams, a flat hem, and lack of a tag add to overall comfort, as does this shirt鈥檚 ridiculously lightweight feel on the body.

鈥淟oved the material. It’s loose, super ventilated and fits well throughout,鈥� raved a tester. 鈥淓xcellent performance,鈥� said another.

Softest Tank

Rabbit EZ Tank

Sizes: XXS-XXL

Pros and Cons
鈯� Super soft and comfortable
鈯� Bonded seams
鈯� Runs small (size up!)

Lab Dry Time: 4 (1=worst; 5=best)
Lab Air Permeability: 2 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

Talk about buttery soft. This tank is made from the brand鈥檚 recycled polyester/spandex blend that feels like your favorite old cotton t-shirt, softened in the wash after decades of use. But unlike cotton, this material dries quickly after being soaked in sweat. While the material might not be as breathable as some other techier-feeling tanks or tees in this roundup, it feels fantastic on the skin and still performs even when damp. 鈥淭he softness and overall comfort made up for the lack of breathability,鈥� said a tester. 鈥淚t’s become one of my favorites. It’s just very 鈥榚z鈥� to wear.鈥� We find ourselves reaching for this tank, and the Rabbit EZ Tee, for lounging; it鈥檚 that comfortable.

Bonded seams around the armholes and neckline remained soft and proved irritation-free for our team of testers.

Softest Tee

Oiselle Flyout Boxy Short Sleeve

Sizes: 2-14

Pros and Cons
鈯� Great combo of style and function
鈯� Great range of sizing
鈯� Takes longer to dry than some

Lab Dry Time: 3 (1=worst; 5=best)
Lab Air Permeability: 4 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

This comfortable, functional tee converted more than one non-crop-top-wearing tester into big fans. The polyester/lyocell/spandex fabric felt fantastically soft next to the skin and kept us dry when we sweat鈥攖he fabric effectively moves moisture to the outer layer where it evaporates. (While the sweat doesn鈥檛 stay against the body, it does seem to remain on the shirt鈥檚 fabric for longer than some quick-dry materials.)

The boxy, crop-style cut adds airflow. We loved it when paired with high-rise thin tights on warm runs and appreciated the cut for gym workouts. 鈥淚 liked how I could see my toes in a plank!鈥� said one.

How To Choose a Running Top

When it comes to summer running clothes, look for comfort, breathability, moisture-wicking, and a chafe-free fit.

Comfort

Aside from chafe-free seams and a cut that allows full arm movement without restriction, consider how the tank or tee makes you feel. Are you comfortable wearing the top both on a run and stopping for coffee afterward? Are you looking for a tank that makes you feel fast on raceday? Do you want a tee that also makes you feel comfortable鈥攂oth in function and style鈥� in the gym?

Materials

Breathable, sweat-wicking materials are essential, as is how the material feels against your skin. While some fabric blends prioritize breathability and quick-drying, others provide a more cottony feel鈥攖he latter sometimes stay wet from sweat longer than the prior, but the tradeoff is sometimes worth it. All tops in this round up perform great on the run.

Fit

The fabric, cut, and seam placement should not restrict your arm movement or your breathing. The best-fitting tops let you forget that you鈥檙e wearing them. Some will fit looser or boxier around the middle, while some have a more streamlined fit. Consider what you鈥檙e after and shop from there. (Our guide describes the fit of each top.)

Tanks vs Tees

T-shirts provide more coverage and therefore more sun protection, and they can also deliver more of a cooling effect, depending on the fabric and fit. Tank tops are typically less restricting and more breathable, because of their lack of sleeves. That doesn鈥檛 mean all tank tops have freedom of movement. Some fit more streamlined around the midsection than others, while some are looser. The looser ones tend to allow airflow, while the more narrow silhouettes depend on their fabrication for breathability. In addition to fit, consider how much skin exposure and coverage you鈥檙e comfortable with, and how the tank interacts with your sports bra and running vest, if you鈥檒l be wearing one. And consider all the settings where you鈥檒l want to wear the top, both athletic and casual.

How We Test

• Number of testers: 8
• Number of products tested: 75
• Number of miles logged while testing: 2,500

We tested as many different shorts, tanks, tees, and other kinds of summer apparel (like sun shirts and crop tops) as we could get our hands on between June and October 2024, with an eye toward products that would be new to consumers in 2025. Our testers ranged in age from 20 to 40, each with more than a decade of running experience and at least one ultramarathon under their belt. We evaluated products by comfort first, followed by style, utility (ability to multitask as casual wear was a big plus), and durability. We also compared the new shirts to those test in the previous year and retained any that were still available and performed better than anything new in their categories.

How We Tested Running Shirts in the 国产吃瓜黑料 Lab

Air Permeability

Air permeability is a measure of how much air (in volume) is able to move through a fabric. It is not the same as “breathability” which measures how moisture vapor (sweat) moves through a fabric. The more air permeable, the more the cooling breeze makes it through your shirt and reaches your skin directly. To test this in the 国产吃瓜黑料 Lab @ CU Denver, we use a James Heal AirPro, a machine that uses a vacuum pump to pull air through fabric clamped between plates with a specific diameter opening to measure the flow rate at a pre-set pressure. The greater the volume of air getting through, the more air permeable. This lab test only evaluates the material itself, and can’t account for how the cut and design of a garment aids its airiness.

Dry Time

The lab tested drying time by soaking each shirt and then recording how long each needed to dry. Each shirt was weighed while dry, then soaked in tap water until all of the material had absorbed water. After soaking, they were hand wrung until all excess water stopped releasing from the fabric, leaving a fully saturated, but not soaked, shirt. The saturated shirts were weighed again to get the “wet” starting point and then put on a mannequin to dry. Weight was recorded every hour to start and then every 15 minutes as they approached dryness, stopping when the sample was within 4 percent of the original dry value. Allowing for 4 percent of weight gain (a few grams) takes into account any dirt particles that could be introduced from the tap water or environment, and small hemmed areas of the shirt that may hold a little moisture, even though the overwhelming majority of the shirt is dry.

We compiled the raw data into groups of similar values for each measure to obtain scores of 1 to 5, worst to best, relative to all the t-shirts and singlets tested.

The post The Best Running Shirts and Tank Tops for Women: Field and Lab Tested appeared first on 国产吃瓜黑料 Online.

Running during the summer can be exhilarating (all that daylight!) and daunting (all that sweat!) at the same time. Whether you embrace the heat and humidity of summer running or long for a return to cold, dark winter days, the right running top can keep you cooler and drier while making you feel fast and fashionable. To help you decide what to wear, we tested over 50 t-shirts and tank tops to find the best men’s summer running shirts.

Update May 2025: We selected new winners in nine categories, including a new best overall t-shirt pick from Arc鈥檛eryx. We also added objective lab measurements on air permeability and dry time to help you select the best summer running shirt for you.

Pros and Cons
鈯� Silky smooth feeling
鈯� Suburb mobility
鈯� Saturates with moisture easily

Lab Dry Time: 5 (1=worst; 5=best)
Lab Air Permeability: 1 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

There’s something about a light, airy singlet that makes us feel fast. No other singlet captured this sensation better than the Adidas Adizero Running Singlet. Made from a thin, lightweight blend of 86 percent recycled polyester and 14 percent elastane, the texture feels phenomenal鈥攕mooth and silky, easily moving over the skin. Testers praised its soft touch and barely-there sensation, with one noting it as 鈥渢he lightest and most comfortable singlet I鈥檝e ever worn.鈥�

The fit is slightly slim, but thanks to the stretchy fabric and side slits at the hem, the singlet offers exceptional mobility. Lead tester Cory Smith says, 鈥淚鈥檓 typically between a men鈥檚 small and medium, but since I prefer a slightly looser fit, I went with a medium that fit that bill perfectly.鈥�

The entire singlet has tiny holes in the face to enhance breathability of the tight weave, which testers said let moisture out, but the lab noted doesn鈥檛 allow much breeze through. Testers also said that the fabric tends to stick to the skin when fully soaked through. It did, however, have the fastest dry time among all the singlets we tried, which helped make this stylish, comfortable singlet stand out as one of the best all-around.

Lab Air Permeability: 5 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

With its silky smooth texture and featherlight feel, we found ourselves reaching for the Hoka Airolite Tank time and time again. 鈥淚 couldn鈥檛 find a single thing to ding this tank on鈥擨 love it,鈥� raved one tester. Crafted with a pinhole mesh, composed of 72 percent recycled nylon and 28 percent elastane, it was one of the thinnest and most delicate tops we tested, making it disappear on the run.

The featherlight fabric wicks moisture efficiently but can become saturated quickly. However, thanks to its minimal weight, even when it was clingy, it never felt heavy or weighed down. In the lab, the Airolite achieved the highest score in air permeability and second highest in dry time. Naturally, its ultra-light design raised concerns about durability. However, after months of wear and repeated washes, one tester was pleasantly surprised by how well it held up.

The tank is 鈥渃ut is long and slim, with just the right width and length of shoulder straps,鈥� noted a tester. One potential drawback is its semi-transparent fabric, but, despite that, we were pleasantly surprised to discover it offers UPF 40+ sun protection. As an added bonus, it鈥檚 treated with an anti-microbial finish鈥攕omething we didn鈥檛 notice in testing but is nice to know it鈥檚 there.

With its smooth texture, near weightless design, and added sun protection, the Hoka Airolite Tank delivers on both comfort and performance. While its ultra-thin, see-through design may not be for everyone, those who prioritize weightlessness and freedom of movement will find it hard to beat.

How We Tested Running Shirts In the 国产吃瓜黑料 Lab

Tester Scott Douglas says, 鈥淭his ultralight marvel is the best singlet I鈥檝e run in during my 40+ years in the sport.鈥� The fit is slim but not restrictive, with plenty of stretch. The bluesign-certified nylon/elastane blend incorporates coldblack, a Schoeller Textil technology that reduces heat absorption like nothing else he鈥檚 experienced. As someone who can lose 5 of his 130 pounds on an easy hour run in Maine, he says, 鈥淚鈥檓 used to wringing out gear post-run and leaving large puddles. This simply wasn鈥檛 possible when I wore the Strata; although my shorts and socks were drenched, little sweat had collected on the singlet.鈥�

And then there鈥檚 its odor resistance: Douglas ran at least an hour in it every day without washing it during one of summer鈥檚 hottest, most humid weeks. 鈥淚t smelled the same on Day 7 as on Day 1,鈥� he marveled. The Strata is expensive, but a good value, given that owning one eliminates the need for all but maybe one other singlet.

Best for Race Day

SOAR Race Vest

Sizing: XS-XXL

Pros and Cons
鈯� Extremely breathable, perfect for hot, humid conditions.
鈯� Featherweight design
鈯� Runs small

Lab Dry Time: 5 (1=worst; 5=best)
Lab Air Permeability: 5 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

Displaying the precision and craftsmanship of a top runway fashion design, SOAR鈥檚 Race Vest stands at the peak of high-performance running apparel. If you鈥檙e looking to turn heads come race day, this is sure to draw attention. 鈥淚鈥檝e gotten more compliments wearing this tank than any other singlet,鈥� says lead tester Cory Smith.

The singlet is made with an Italian-made open mesh fabric that鈥檚 razor-thin and extremely breathable. Even on the hottest, most humid days, body heat escaped effortlessly, while the airy design allowed any breeze to pass through for cooling relief. The lab confirmed the vest鈥檚 airyness: It blew away the field in air permeability and also earned the highest score in dry time.

The only drawback we found was that the fabric doesn鈥檛 absorb and wick moisture as well as thicker materials. However, its sheer lightness let skin dry and cool without pulling sweat away from it.

Premium touches like laser-cut and bonded seams eliminated chafing during our test. With many singlets, the shoulders can shift while running, creating a distraction鈥攂ut not with the SOAR Race Vest. The straps lay flat and stay securely in place. The slim-cut design sits close to the skin and runs small, so if you prefer a more relaxed fit, we recommend sizing up.

How We Tested Running Shirts In the 国产吃瓜黑料 Lab

Blending form and function, this shirt wowed our testers with its performance. Despite being marketed as a mountain running shirt, we found it well-suited for runs on any terrain.

The front features a silky-smooth polyester fabric that鈥檚 DWR-treated, excelling at both repelling moisture and wicking it away from the skin. The face fabric feels incredibly smooth and luxurious, gliding against the skin without friction, flowing naturally with every stride. Although the shirt had average lab marks on air permeability and dry time (relative to the other top T鈥檚 in this guide), it never felt weighted down, even when saturated with sweat. Meanwhile, panels under the arms and the entire back are made of an airy mesh, allowing more airflow in high heat areas鈥攚hich we especially appreciated when wearing a hydration vest.

Subtle details distinguish the Norvan Downword from cheaper options, including a tailored fit, laminated neckline, and smoothly finished seams and hems. Plus, a silver ion polymer coating effectively fights bacteria and odors.

One of our biggest pet peeves is when a shirt rides up during arm movements. Although the Norvan Downward鈥檚 fit is trim with a slightly shorter hem length, thanks to the articulated sleeves and split sides, we found the hem stayed put on the run.

Soft, stretchy, and impressively moisture-wicking, the Rabbit EZ Tee takes comfort to a new level. Our testers said it quickly became a go-to for nearly any activity, including everyday wear. Made with a simple, soft polyester and spandex blend with a UPF 50 rating for sun protection, it鈥檚 a shirt you鈥檒l want to keep on post-run for its comfort and style, whether you鈥檙e grabbing coffee or heading to the gym.

Testers appreciated the EZ Tee鈥檚 tailored cut, which offered a comfortable fit that felt neither restrictive nor clingy. One tester described it as 鈥渏ust right鈥攏ot too short, too tight, or too loose.鈥� Thoughtful details, such as raglan shoulders and flat-lock stitching, showcase the attention to detail put into this shirt.

Our only complaint? The limited color options. 鈥淚 could comfortably, confidently buy seven different colors and run in nothing else,鈥� said one tester. And the price is so reasonable that stocking up is a feasible option.

Best Value

Terignota Trail Tee

Sizing: XS-XXL

Pros and Cons
鈯� Extremely lightweight
鈯� Outstanding price-to-performance
鈯� Limited color options

At nearly a third of the cost of other options, you will not find a higher quality shirt at a better price. Crafted from 100 percent polyester with a woven grid pattern, it checks all the boxes: lightweight, breathable, and comfortable. Its woven design and thin fabric reminded us a lot of Patagonia鈥檚 Capilene for a fraction of the price.

Despite being marketed as a trail tee, it鈥檚 equally suitable for the roads. Throughout the warm, sunny SoCal summer, it kept me cool and comfortable, proving to be a versatile go-to for any tempo. After hot and sweaty runs, I was impressed with how quickly the shirt dried in direct sunlight. With a 4 out of 5 in both dry time and air permeability, the Terignota had the highest combined lab score of any tee we tested.

The fit is labeled as relaxed, but I found it slightly on the slim side compared to other shirts in our lineup. It鈥檚 not enough to size up, but I wouldn鈥檛 call it a true relaxed fit.

Best Splurge

SOAR Advanced Tech Tee

Sizing: S-XXL

Pros and Cons
鈯� Fantastic range of motion
鈯� Extremely breathable
鈯� Short hem length

Lab Dry Time: 5 (1=worst; 5=best)
Lab Air Permeability: 1 (1=worst; 5=best)

London-based SOAR founder Tim Soar says he incorporates his passion for functionality, performance, and sports science into every design, and the Advanced Tech Tee is a prime example of this.

At first touch, the ultralight, stretchy 3D woven fabric felt 鈥渁 bit stiff and scratchy,鈥� according to one tester. But that impression didn鈥檛 last long. 鈥淚t disappeared once I started running,鈥� he said. 鈥淚 actually feel cooler and more comfortable in this than going shirtless.鈥� The fabric鈥檚 subtle stretch and textured weave made it stand away from the skin and stay dry, even when we were sweating profusely. Surprisingly, the lab reported that the tight fabric doesn鈥檛 let much air through, but it has the fastest dry time of any shirt or singlet tested, quickly evaporating moisture.

Additional touches, such as a split hem and one-piece raglan sleeves, enhance freedom of movement, while laser-cut sleeve hems and flat-locked seams reduce potential chafing.

The tee boasts a relaxed fit but leans more toward a European cut鈥攕lightly fitted through the shoulders and chest, with a bit more room through the torso for ease of movement. My only wish is that the hem was a little longer to better accommodate those with longer torsos who prefer more coverage.

Best Wool

Ridge Pursuit Ultralight Merino Tee

Sizing: S-XXL

Pros and Cons
鈯� Fantastic moisture-wicking abilities
鈯� Natural odor-resistant
鈯� Wool is an acquired taste

When you think of a warmer weather running shirt, wool may not be the first fabric that comes to mind. Most people equate wool with cold weather. But wool, which is naturally both extremely breathable and moisture-wicking, is just as effective in hot conditions as in cold. After testing over six wool shirts, testers all found the Ridge Pursuit Merino Tee the best. 鈥淭his is the closest to my gold standard,鈥� said one tester with an extensive wool collection.

Thoughtful attention was given to every detail, from gusseted sleeves for improved range of motion to a one-inch drop tail for added coverage. Merrow stitching along the side seams ensures a smooth, flat finish to help prevent chafing. The patented Merino wool yarn is engineered to be lighter and stronger and said to deliver twice the durability of traditional 100 percent Merino wool apparel. Testers said it was noticeable. Where most wool shirts we tested felt delicate and lost shape easily, the Ridge Pursuit Merino was more resilient, maintaining its structure even after repeated wear and washing. The merino wool is so naturally odor-resistant, however, you won鈥檛 have to launder it often: One tester found that the 鈥淧ursuit tee can go five runs before it needs to see the hamper鈥濃€攁 boon for those who feel the pain of a never-ending laundry cycle.

With its thoughtful design, durability, and natural benefits, one tester said the Ridge Pursuit Merino Tee strikes 鈥渢he delicate balance of performance, comfort, and value that has long eluded the Merino market.鈥�

Best for High Heat

Montane Dart Nano T-Shirt

Sizing: XS-XXL

Pros and Cons
鈯� Remarkably lightweight
鈯� Airy
鈯� Limited moisture absorption due to thin fabric

Lab Dry Time: 3 (1=worst; 5=best)
Lab Air Permeability: 4 (1=worst; 5=best)
How We Tested Running Shirts In the 国产吃瓜黑料 Lab

The Montane Dart Nano comes as close as possible to the feeling of running shirtless.鈥淚t鈥檚 lightweight to the point of near-invisibility,鈥� said one tester. Made with 100 percent recycled polyester and weighing a mere 2.8 ounces, the thin fabric allows for excellent airflow. During sweltering runs in the hot and humid Northeast summers, one tester reported his body heat escaped effortlessly through the material, which, he said, 鈥渢ransformed scorching runs into manageable experiences.鈥� Another tester said, 鈥淚t鈥檚 the shirt you鈥檒l reach for without hesitation when the temperature soars.鈥�

The cut is trim, sitting close to the body, but doesn鈥檛 feel suffocating thanks to the featherlight fabric and added articulation, which includes extra room around the underarm so the sleeve won鈥檛 ride up even when your arm is extended. However, the ultra-thin material comes with two drawbacks: It doesn鈥檛 absorb and wick moisture as effectively as some other options and provides minimal warmth on cooler days. But, in the most extreme warm-weather conditions, this ultralight tee offers exceptional breathability and comfort.

Best Road-to-Restaurant

Lululemon Metal Vent Tech Short-Sleeve Shirt

Sizing: XS-XXL

Pros and Cons
鈯� Suburb range of motion
鈯� High-quality fabric
鈯� Not as good at dealing with heat as lighter, more breathable fabrics

Best suited for runs that start at the track and end at the cafe, the Lululemon Metal Vent Tech blends performance and style with a timeless, refined design. 鈥淚t seamlessly transitions from morning runs to evening restaurants with uncompromised excellence,鈥� one tester reported. Made from a nylon, recycled polyester, and elastane blend, this shirt has a heavier, more substantial feel than the thinner options we tested. It doesn鈥檛 vanish like ultra-lightweight shirts but instead offers a noticeably soft and comforting feel against your skin.

While it鈥檚 not a particularly airy shirt, we found it does breathe and wick moisture adequately to not feel clammy on most days. And, thanks to the built-in stretch, the shirt offers an unrestricted range of motion and doesn鈥檛 hold you back on the run. On extremely hot days, however, when sweat is pouring and the fabric becomes fully saturated, it can feel slightly weighed down.

Given its versatility and comfort, the Lululemon Metal Vent Tech became one of our go-to shirts for just about any occasion, from running to lounging at home to heading out for a casual dinner.

What to Look For in Summer Running Apparel

Dressing for summer running is straightforward鈥攜ou want pieces that breathe, wick moisture, move naturally, don鈥檛 stink, and don鈥檛 get in the way. Shirt choices come down to how much skin coverage you prefer, fit, and material.

Here are some quick tips on buying the best without going broke:

• Look for high-quality synthetic fibers. Yes, our top picks include a few items with natural fibers. But for the most part, specially designed varieties of polyester, polyamide, nylon, and the like can handle summer running鈥檚 high sweat rates better than wool and cotton.
• Seek sun protection. Even if you run at dawn or dusk, or on trails, sun damage can be insidious. Many shorts and tops come with a UPF coating. Well-ventilated hats reduce squinting while shedding heat. Running tan lines aren鈥檛 something to be proud of.
• Check for chafing. If you鈥檝e ever been rubbed raw by a rigid seam or sagging liner, you won鈥檛 want to repeat the experience. Abrasion accelerates when you鈥檙e drenched in sweat. Look for flat seams, unobtrusive logos, and other elements of construction that will minimize chafing.
• Go with the flow. Our picks in this review strike the right balance between being loose enough to allow cooling air flow but not so billowy that they impede normal running form.
• Banish bacteria. Many high-quality summer running items incorporate an anti-bacterial treatment that greatly reduces nasty odors setting up shop. These pieces not only can be worn many more times before needing to be washed, but also lessen your chance of developing a funky skin situation.
• Invest in quality. It can be tempting to think, 鈥淲hatever I run in is going to get soaked anyway, so I鈥檒l just buy the cheapest gear out there.鈥� Such reasoning quickly falls apart when, well, the item itself starts to fall apart because of constant exposure to sweat and frequent laundering. Fewer high-quality pieces that hold their form and don鈥檛 hold odors are better than more cheaply made gear that will start disintegrating in one summer.

How We Test

• Number of testers: 10
• Number of products tested: 20+ singlets, 40+ short sleeve tees
• Number of brands tested: 45+
• Number of miles run in testing: 4,500+
• Highest testing temperature: 101 Fahrenheit
• Number of 国产吃瓜黑料 Lab tests: 2

Our testing team ranged across the U.S.鈥攆rom the California beach town of Santa Barbara to central Wisconsin and the high plains of Nebraska, to the urban bake sites of Chicago and Houston, and, for good measure, the running hub of Eugene, Oregon. All are dedicated runners with average weekly mileage ranging from low 20s to mid-70s over both roads and trails. Some have been running for 30 or more years and can compare today鈥檚 running apparel to previous attempts to keep runners cool in the summer. We focused on a subjective combination of moisture management, comfort, versatility, value, and looks to answer a simple question: Of all the apparel you logged summer miles in, which would you be most likely to recommend to fellow runners?

How We Tested Running Shirts in the 国产吃瓜黑料 Lab

Air Permeability

Air permeability is a measure of how much air (in volume) is able to move through a fabric. It is not the same as “breathability” which measures how moisture vapor (sweat) moves through a fabric. The more air permeable, the more the cooling breeze makes it through your shirt and reaches your skin directly. To test this in the 国产吃瓜黑料 Lab @ CU Denver, we use a James Heal AirPro, a machine that uses a vacuum pump to pull air through fabric clamped between plates with a specific diameter opening to measure the flow rate at a pre-set pressure. The greater the volume of air getting through, the more air permeable. This lab test only evaluates the material itself, and can’t account for how the cut and design of a garment aids its airiness.

Dry Time

The lab tested drying time by soaking each shirt and then recording how long each needed to dry. Each shirt was weighed while dry, then soaked in tap water until all of the material had absorbed water. After soaking, they were hand wrung until all excess water stopped releasing from the fabric, leaving a fully saturated, but not soaked, shirt. The saturated shirts were weighed again to get the “wet” starting point and then put on a mannequin to dry. Weight was recorded every hour to start and then every 15 minutes as they approached dryness, stopping when the sample was within 4 percent of the original dry value. Allowing for 4 percent of weight gain (a few grams) takes into account any dirt particles that could be introduced from the tap water or environment, and small hemmed areas of the shirt that may hold a little moisture, even though the overwhelming majority of the shirt is dry.

We compiled the raw data into groups of similar values for each measure to obtain scores of 1 to 5, worst to best, relative to all the t-shirts and singlets tested.

I live in New York City, where it is a commonly held belief that people walking four abreast on a public sidewalk deserve summary execution. I also run in New York City, often alone but just as often with run clubs鈥攊n other words, in groups of as few as four or as many as a hundred, and on the same extremely crowded streets. And as run clubs grow in popularity, so does the potential for conflict or, at the very least, bad vibes.

Urban run clubs are easy to hate. Early on Saturdays and Sundays, when our fellow citizens are schlepping bleary-eyed in search of coffee, we are bright, fit, and in their faces, breaking the morning calm by shouting 鈥淗eads up!鈥� in our best coach voices. On weekday evenings we鈥檙e out in force as well, flaunting our energy levels and shaming the office workers desperately trying to get home or to a bar. Run clubs have themes that veer from the quotidian (neighborhood, ability, identity) to the easily mocked: Runs that end at a taqueria! Run clubs for singles! Run clubs that aren鈥檛 overtly for singles but are, tbh, really for singles! The group selfies for the 鈥榞ram, the branded merch, the giveaways of goos and gels, the after-parties鈥攊t鈥檚 all a bit much.

(Even I hate run clubs at times, and I run a run club! The Not Rockets, which, you will be pleased to learn, has no social media presence.)

A lot of the hate is simply about space. Any city worth living in doesn鈥檛 have enough of it, so anyone visibly occupying it becomes a target. One group of 50 runners on a riverside esplanade causes a brief bottleneck. Half a dozen such groups running simultaneously provokes outrage鈥攁nd not just because pedestrians are afraid they鈥檒l be trampled by Hokas. It鈥檚 also because, for as long as we runners are there, swarming around the non-runners, we are a hot, sweaty, unignorable sign that no one here has enough room to breathe.

No one expects this to change either radically or soon. After all, New York and other cities鈥攆rom London to San Francisco鈥攈ave always been experiments in density: How many people can you cram into tiny apartments and narrow streets before they start murdering one another? The answer, surprisingly, is 鈥渕illions and millions.鈥� It turns out, we like living this way. As crime rates have dropped nearly everywhere since the 1990s, it feels as if we鈥檝e learned that we can actually get along, despite our infinite differences, by (mostly) trying not to mess with people unnecessarily and also by trying (mostly) not to freak out too badly when someone messes with us unnecessarily.

One of the ways we manage this is by complaining: to friends, co-workers, whoever sees us for twenty-four seconds on their FYP. Run clubs are just the latest, trendiest subject to kvetch about, and it’s my contention that the loudest complainers in fact love run clubs for giving them such a meaty, persistent topic to post about鈥攋ust as runners themselves love to whine about double-wide strollers, lost tourists, and inattentive dog-walkers. It’s a release that allows us all to feel equally self-righteous, to feel that the city belongs to us, whoever we may be, if only for a moment. Because in the backs of our minds, we know who it truly belongs to, the common enemy at which we鈥攔unners and non-runners alike鈥攔eally should direct the full force of our ire, our anger, our hatred: cars.
