Featherlight alpine armor that laughs at mountain storms. Arc'teryx's toughest shell pant weighs just 7.8oz but shrugs off anything the peaks throw at you.
When the mountain weather turns nasty, the Arc'teryx Alpha Pant delivers bomber protection without the bulk. Built with revolutionary Hadron 3L GORE-TEX fabric, these alpine climbing pants weigh just 220g while providing the same abrasion resistance as much heavier mountaineering pants. The patent-pending waist cinch system sits comfortably under your harness without loosening during technical climbs, while full-separating side zips let you pull them on over boots and crampons in seconds. Articulated knees and a gusseted crotch give you the freedom to make those high steps and mantles, whether you're tackling mixed routes or pushing through unpredictable alpine conditions. At 28,000mm waterproof rating, these pants will keep you dry when the weather window slams shut, making them essential gear for alpinists who demand lightweight reliability in rugged mountain environments.
