The Mammut Nordwand Pro HS Hooded Shell Jacket is specially designed to give us reliable protection as we climb higher into the alpine zone on exceptionally technical routes. Whether we're mountaineering or ski touring, the hardshell jacket is fully featured to ensure we stay dry and comfortable with a helmet-compatible hood, zip-off snow skirt, and intentionally placed pockets that are accessible while we're on belay. GORE-TEX PRO waterproofing blocks wind and snow from cutting through our layers, and the incredible breathability helps to move sweat away from our skin while we're working hard. On grueling climbs, we can open the underarm vents to circulate air without having to sacrifice any protection from the elements.
