There鈥檚 been a lot of upheaval in this category recently. The race to create the lightest, most breathable鈥攂ut still bomber鈥攋acket has destroyed longstanding paradigms. The lines that once divided soft and hard shells have blurred so much, they鈥檙e all but gone. Waterproof down has gone from pipe dream to commonplace, while new lightweight synthetic insulations keep you warm on the coldest days. Now, in another leap forward, mad-scientist engineers are using surprising new materials like corn (that鈥檚 right, corn) and rain-shedding wool. The upshot? There are more high-quality jacket options than we ever thought possible.

Gear of the Year
Companies have tried for years to make a puffy you put on and keep on, whether you鈥檙e at camp or on the hill. Patagonia pulled it off with the Nano-Air, a breathable insulator that won our Gear of the Year last season. Now OR has perfected the concept. Filled with Polartec Alpha (made to keep U.S. Special Forces dry during combat), and wrapped in a cozy face fabric, the sheds snow and moves moisture away from the body. The best puffy here for high-output activity, it worked for all our winter pursuits, from skiing to hiking. Bonus: inside pockets swallow gloves and a hat. 1.2 lbs

Patagonia Refugative聽
Best For: Going fast and far.聽
The Test: You鈥檙e moving constantly in the backcountry, which means your shell spends most of its time in a pack. Read: you want it to be as light as possible. Here, it鈥檚 tough to beat the . Cut from Gore鈥檚 svelte new C-Knit-backed fabric, this minimalist jacket weighs less than a pound but still shields you in a storm and comes with niceties such as 14-inch-long pit zips and four roomy pockets. We pack it in our bag even on bluebird days as a barely-there insurance policy.聽
The Verdict: A sleek hard shell perfect for three-season use. 15 oz

Dynafit Yotei GTX聽
Best For: Ski touring.聽
The Test: The 鈥攎ade from the same high-end fabric as the Patagonia鈥攊s built specifically for people who log lots of miles on all-day ski tours. Hence backcountry-specific features like huge chest pockets that accommodate climbing skins while still playing nice with pack straps. Vents over the triceps dump heat in a hurry, and even though the removable powder skirt and stretchy wrist cuffs add a few ounces, we appreciated those extra features on the coldest, deepest days.聽
The Verdict: 鈥淭he perfect backcountry ski shell,鈥 said one tester. 1.2 lbs

Berghaus Baffin Island聽
Best For: Multisport play.聽
The Test: Sure, the looks like your classic trim-cut European hard shell, but it鈥檚 actually an extremely versatile layer suited to everything from ski touring to bike commuting. Stretchy fabric at the back and under the arms gives it the non-restrictive fit of a supple midlayer, while burly material at the shoulders and hips boosts durability without adding much weight. Berghaus nailed the details, too, including a drop hem that鈥檚 long enough to keep you dry even running rainy-day errands on a bike.
The Verdict: A do-it-all mountain parka at a great price. 1.1 lbs

The North Face Summit L3聽
Best For: Extreme insulation without the weight penalty.聽
The Test: The 800-fill down comes in well under a pound and scrunches down smaller than a grapefruit. Built with FuseForm, which combines various yarn types into a single material, it has fewer seams than its competitors, boosting durability while reducing weight. The fabric is three times as strong at the shoulders and hips as at the torso, making the L3 tough where you need it to be and breathable where you don鈥檛.聽
The Verdict: A gossamer hoodie you can鈥檛 afford not to throw in a pack. 12.7 oz

Ortovox Piz Boe聽
Best For: High-output action.聽
The Test: In the ongoing arms race to make an insulator that keeps you warm (but not too warm) in wet conditions, Ortovox came up with a surprising weapon: corn. It filled the with an absorbent blend of wool and a cornstarch-based polymer. It sounds like a Shackleton survival strategy, but it works brilliantly. We stayed toasty even during a 38-degree run in the rain. The nylon shell is windproof, while stretchy merino panels on the arms keep this piece snug without inhibiting movement. Nice touch: the mesh-backed pockets do double-duty as chest vents.聽
The Verdict: Ideal for skiing, running, climbing, and biking in the sleet. 12.7 oz

Voormi Fall Line聽
Best For: Wool lovers.聽
The Test: Most shells are content to sandwich a membrane between two pieces of fabric to keep out water. The , on the other hand, uses Voormi鈥檚 Core Construction technology, which weaves wool through a waterproof sheet. Result: a single-layer jacket with the wind- and snow-shielding abilities of a soft shell but the feel of fleece. The breathable top repelled sloppy cement, but without taped seams it didn鈥檛 keep us dry in a downpour.聽
The Verdict: A surprisingly stylish high-performance piece. 1.8 lbs
