Fully dialed for demanding ski lines from the Chugach to Chamonix, the Black Diamond Cirque 45 is our technical ski mountaineering pack with a large-sized capacity for big missions and overnight trips. The Cirque’s minimalist construction features an active suspension, as well as our unique CINCH closure system that opens or closes the top with a single pull. A slide-in avy tools pocket and rope and ice tool attachments secure all your gear, while a quick-deploy piolet system that is compatible with piolets, technical tools and mixed tools comes in handy during unexpected sections of no-fall terrain.
