The Mammut Stoney HS Jacket is a full-feature ski shell that doles out plenty of all-weather protection, thanks to its Mammut DRYtechnology Pro membrane. It features plenty of stretch for better mobility on the mountain, and it's also outfitted with a powder skirt, helmet-compatible hood, and plenty of pockets for our goggles, ski pass, and devices to keep us skiing and snowboarding to our heart's content.
