Built for multi-day missions in the mountains, the Ortovox Peak 55L Backpack delivers durability and comfort for alpine climbing, mountaineering, and ski tours. The pack features an abrasion-resistant nylon shell with 55 liter capacity for our sleeping bag, tent, crampons, and extra layers, plus external attachment points for our rope, poles, ice axes, helmet, skis or snowboard. The padded harness and hipbelt help us haul gear for overnighters and huge day trips while the SWISSWOOL 3D Back System has a close-to-body fit and metal braces to help us wear our load well.
