Along the Aleutian coast, a williwaw isn’t something taken lightly. It’s a mass of cold, dense air that rushes off the mountains – bringing slashing sleet and vessel-tipping waves along with it. It’s a massive wrench in the workday, but it can be tamed with the right gear. The Williwaw Stretch Shell borrows the best in technical skiwear to make it happen. The two-layer fabric is 100% waterproof and breathable, wind-stopping and completely seam sealed. Made for mobility in durable, seriously stretchable fabric plus articulated elbows that never bind when you reach. Stretch storm cuffs plus toggle cinch hem keep rain and biting wind from creeping in. And when whiteout conditions come rolling in, snap the Aniak Jacket inside for goose-down warmth that won’t weigh you down. You can’t change the weather. But with a Williwaw Shell, you can damn near ignore it.
