Despite being one of Black Diamond's lightest, the Cirque 35 Backpack boasts enough space for backcountry tours and ski mountaineering missions. For minimalist 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. The SwingArm shoulder straps and stretch waist belt provide active suspension and a streamlined fit.
