Despite being one of Black Diamond's lightest the Cirque 35 Backpack boasts enough space for backcountry tours and ski mountaineering missions. Designed for minimalists backcountry skiers and ski mountaineers the Cirque features only the basics but still retains a full-featured design. It carries skis diagonally or at an A-frame as well as your helmet avalanche safety gear ice axes and even a climbing rope. Although streamlined for minimalists the Cirque still sports innovative technology that doesn't add a whole lot of weight to your back. The SwingArm shoulder straps and stretch waist belt provide active suspension and a streamlined fit. The Cirque is compatible with Black Diamond's AvaLung and SilNylon lid pocket for added safety and capacity when traveling in avalanche terrain.
