The mountain bike market continues to segment and specialize, encompassing everything from drop-bar rigid rides聽for events like the Tour Divide聽to bikes with 200-millimeters-plus of travel for hurling down cliffs at the Red Bull Rampage. Likewise, apparel is becoming more varied. The three kits listed below all feature聽smart,聽innovative details, which is why they鈥檝e聽found their way to the top of my kit drawer. 聽
Troy Lee Designs Ace Jersey聽and Ace Short Elite ($68 and聽$165)

Troy Lee Designs built its reputation on gravity and motocross, but it launched into the XC market this year. That鈥檚 a聽bold move given the general disconnect between the gram-counting crowd聽and the loose-cut, bold-patterned downhill market.
TLD assures us it won鈥檛 be going full Lycra anytime soon, but the well-tailored cut of the Ace line shows they did their homework. The silky-feeling is trim and built from a moisture-wicking synthetic that聽kept me cool even on searing New Mexico afternoons. The fabric is UPF 50 for ultraviolet protection, too. The trio of pockets on the back is big enough for the necessary sundries聽and there鈥檚 even some reflective details for nighttime safety.
The are figure-hugging, but the 10-percent Spandex blend kept them comfy and free-moving. The padded waist adjusts via two Velcro tabs, and there鈥檚 a small zip pocket out back for a key and credit card. The only real failing is the 鈥減remium鈥 chamois, which is thin and more comparable to a mid- or even budget-level liner in other brands. I generally used my favorite bibs underneath instead.
Bottom Line: High-quality fabrics and fun designs for people who want a bit of flair.聽
Acre Linear jersey聽and Traverse short ($62 and聽$165)

Acre is an offshoot of the urban commuter brand , and it pairs the mother company鈥檚 plain, black hipster aesthetic with looser-cut clothing for the off-road crowd. The has quickly become my hands-down favorite trail short,聽thanks to the fist-width, full-wrap belt design, which is comfy and doesn鈥檛 rub or chafe with a pack. I love the high-quality aluminum buckle, too. The unassuming-looking fabric is light, water-repellant, fast-drying, and still gauzy soft. Pockets are large and sit behind the thighs so as not to interfere with pedaling, and the to-the-knees cut is baggy and works with kneepads. The only downfall? The Traverse doesn鈥檛 come with a chamois, which makes it relatively pricey.
The keeps with the simple theme: it鈥檚 a super-breathable, wicking short-sleeve T-shirt聽that works great,聽but doesn鈥檛 broadcast its cycling cred. And while I love the look and feel, the material has a tendency to snag on branches and brush.
Bottom Line: Technical apparel for the days you don鈥檛 want to look the part.
Assos SS.rallytrekkingJersey_evo7 and T.rallyShorts_s7 ($400 and $450)

Yep, you can buy complete bicycles for a lot less than the full Rally kit. And yes, that will probably strike a lot of people as absurd. But what you get for that large chunk of change is the most highly engineered cycling apparel available, with all the fabrics developed in-house at Assos (and therefore proprietary), plus tailoring and fit that make a custom聽suit look dumpy.
The are outrageously comfortable, with an oversize, free-floating, seamless, multi-density pad that I鈥檝e worn for 48 hours in the saddle with zero chafing. There are two primary fabrics in the rest of the piece:聽a highly compressive wrap in the legs and back that doesn鈥檛 require any seams, and a tougher, abrasion-resistant swathe in the crotch. The bibs straps are wide, soft, and聽elastic,聽crisscrossing suspender-style out back, which staved off sweat even under a pack. There are also removable hip pads that prevented bruising and tearing when I crashed.聽
The is even wilder, with a super-trim, racer fit聽and a back panel constructed of a springy, elastic mesh that, when paired with the bibs, provided the best ventilation under a pack of any kit I鈥檝e ever ridden. It comes with its own base layer ($80 if you purchase it separately) to help with wicking and protect your back from the sun. There are three large pockets out back with reflective stripes, which I feared would rub beneath a pack but somehow did not. All together, the Rally kit doesn鈥檛 feel like apparel so much as a gossamer,聽perfectly equipped piece of equipment鈥攍ike a specialized mountaineering jacket or a聽dry suit.
Bottom Line: The ultimate endurance racing kit鈥攆ull stop. But here鈥檚 the thing: unless you spend days or weeks at a time in the same kit, the money is聽better spent on a wheel upgrade.
