Mammut's Stoney HS Hooded Jacket is a best-seller for a reason, and with a slew of new updates, it's only getting better. The jacket is protected by the completely waterproof DRY Tour membrane, which efficiently transports moisture out of the jacket during ski tours while keeping us dry when we're riding off-piste at the resort. New underarm X-vents help us stay cool while we work our way up the skin track, and soft hand gaiters keep the sleeves in place no matter how hard we're working. The helmet compatible hood is easily adjustable so we can seal out the weather on powder days, and the detachable powder skirt completes the protection so we can lap the mountain on the biggest days of the year.
