Stripped down for technical performance on serious ski lines the world over, the Black Diamond Cirque 30 pack combines the functionality of an ultralight alpine pack with a full ski feature set. The Cirque’s minimalist construction features a sturdy suspension with a removable foam backpanel insert, 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.
