The lightest jacket on the market to utilize Polartec's waterproof-breathable NeoShell fabric, the Westcomb Shift LT Hoody weighs 12 ounces. But that doesn't mean it's light on function: In addition to warding off the wet stuff, the fabric is ripstop enhanced, proving more than able to handle the rigors of the trail. Deep chest pockets hold gear, while long arms allow for full range of motion. [$400; westcomb.com]
