Serious waterproof mountaineering gear, the Powderhorn Gunpowder Down Jacket is professional outerwear designed for freestyle skiers and other winter athletes, that looks good, too. It incorporates highly technical fabrics, ultimate comfort, slope-tested usability features, and they waterproofed the down! Altogether, a totally functional winter wardrobe addition with a ruggedly understated elegant style. For the designer backstory, Powderhorn got its start making snow-proof jackets purpose-built for the extreme freestyle scene, in a backyard factory in Jackson Hole, Wyoming, in 1972.
