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 DRYtechTM 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.
