La Sportiva Storm Fighter GTX Jacket
GEAR OF THE YEAR: Who knew that an Italian bootmaker would be so proficient in the jacket game right out of the gate? The 鈥檚 Active Shell fabric鈥攁 new, lighter-weight version of Gore-Tex鈥檚 most breathable stuff鈥攌ept us bone-dry during three days of nonstop rain along Northern California鈥檚 Lost Coast Trail, and it breathed impressively well as we huffed along Lake Superior鈥檚 North Shore through sideways snow. Smart details like Velcro-less cuffs that slide into (not over) gloves and a tiny magnet at the hem that holds the zipper cover in place made us smile. All that, plus it鈥檚 better looking (love the asymmetrical detail on the shoulder) and just as light as every other hard shell in its class. 11 oz

Arc'teryx Alpha SV Jacket

BEST FOR: Nasty conditions.
THE TEST: The revamped Alpha SV is cut from an up-armored version of Gore's Pro 3L, which you'll also find on Arc'teryx's Gear of the Year-winning resort jacket. Put simply, it's one of the most durable fabrics we've ever tested. Cut a bit looser than your classic Arc'teryx jacket to fit over bulkier winter layers, the SV is near artisanal in its construction, with miniature bellows on the chest pockets so they'll lie flat when empty and foam tubing to keep the hem from riding up under your climbing harness.
THE VERDICT: It's a bit crinkly, which some testers found annoying, and definitvely pricey. But as one tester also noted, “it's the toughest hard shell I've ever worn.” 18 oz
Breathability: 4
Waterproofness: 5
Rab Stretch Neo Jacket

BEST FOR: Doing it all.
THE TEST: 鈥淚f I had to clean out my closet and keep just one shell, it鈥檇 be the .鈥 That remark came after an expedition-style adventure race in Patagonia, where testers trekked and climbed in this jacket for eight days. The key to its versatility is Polartec鈥檚 NeoShell fabric, which breathes as well as any waterproof material we鈥檝e ever worn. The alpine-influenced design includes long arms, a helmet-compatible hood, and two massive pockets on the chest for stowing gloves, glasses, a hat, and a day鈥檚 worth of energy bars.
THE VERDICT: The streamlined design鈥攏o pit zips, no hand pockets鈥攈elps keep weight down, but it鈥檚 not as light as some of the competition. 18 oz
Breathability: 4
Weatherproofness: 4.5
Mountain Hardwear Quasar Pullover

BEST FOR: Packing light, moving fast.
THE TEST: Designed by Swiss speed climber Ueli Steck, is about as simple as it gets, with a small hood that fits best under, not over, a helmet (Steck prefers the close-to-head, under-helmet fit) and a single non-zippered pocket inside the chest. The only real creature comfort is the soft, thumb-hole-equipped cuffs, which are certainly cozy鈥攗ntil they get wet. On damp days, the fabric sponged up water as we climbed.
THE VERDICT: Optimal for anyone looking for a packable, just-in-case hard shell for winter, spring, or fall. 9 oz
Breathability: 4

The North Face Polar Hooded Jacket

BEST FOR: Start-stop activities on cold days.
THE TEST: A unique mashup, the melds soft-shell construction (arms, shoulders, and hood) with low-profile insulated panels (shoulders, biceps, and back) and a swath of fleece around the torso. In single-digit temperatures while skiing and snowshoeing in Minnesota, the stretchy, breathable Polar Hooded regulated temperatures nearly as well as a traditional soft shell. And it was surprisingly warm: during breaks when we鈥檇 normally be reaching for our puffies, it kept us just warm enough on its own.
THE VERDICT: A versatile soft shell with an insulating alter ego. 26 oz
Breathability: 5
Weatherproofness: 3.5
SmartWool PhD SmartLoft Divide Jacket

BEST FOR: Moving quickly in cool weather.
THE TEST: The has a familiar design鈥攁n insulated chest panel with stretchy, breathable material along the back and arms鈥攂ut with a unique twist. Instead of fleece arms and synthetic insulation, it鈥檚 wool throughout, including merino for the arms and back and fluffy wool-based fill for insulation. On sweaty cross-country ski outings and winter runs, the shirtlike, one-pound SmartLoft Divide breathed just as well as its synthetic competition. The jacket鈥檚 core-warming front was balanced by the thin merino elsewhere鈥攚hich, by design, lets wind cut straight through.
THE VERDICT: Aerobic do-all coat that several testers praised as the ultimate winter midlayer. 1 lb
Breathability: 5
Weatherproofness: 1
Sierra Designs Gnar Lite Jacket

BEST FOR: Winter camping; cold and wet outings.
THE TEST: Each goose feather inside the water-resistant is coated with a hydro-phobic treatment marketed to keep the down dry 鈥10 times longer鈥 and, should you still manage to wet it through, dry out 鈥33 percent faster鈥 than old-fashioned feathers. To test those claims, we wore this basic sweaterlike coat鈥攊t weighs a scant 10 ounces and packs to the size of a grapefruit鈥攁s a layer and on its own. During a cold and seriously drizzly March hike, it took about 30 minutes to wet through. Though it did get a big clumpy, the jacket retained some loft (and thus warmth) despite being almost moist enough to wring out a sleeve.
THE VERDICT: The technology (mostly) works. 10 oz
Breathability: 4
Weatherproofness: 3
The trend in insulatation this year is water-resistant down, like the stuff inside Sierra Designs' Gnar Lite. By treating each feather with a special coating, Sierra figured out how to keep down dry up to 10 times longer.
