Mammut Stoney HS Jacket

The Mammut Stoney HS Jacket is a hard-shell fortress you can absolutely depend upon when the weather hits the fan. Sporting Mammut's own DRYtech™ Premium 3L protection and meticulous construction, the Stoney HS Jacket will keep you dry when it's wet and warm, when it's cold (with a mid-layer underneath), and will even let water vapor exit when you're working hard to access that new line.
