The Cirque 45 is the ultimate ultralight long-tour or overnight ski mountaineering pack. Inspired by BD’s ultralight climbing packs, this pack includes all the features needed for a successful backcountry ski tour. The single-pull cinch chord and fold-over lid are secured by a simple single strap that doubles as a rope holder or top attachment for diagonal ski carry. The pack includes an easily accessible avalanche gear pocket with bottom drain holes to allow moisture to escape. Black Diamond’s PickPocket system enables you to attach an ice axe or tool securely and has a Quick Deploy system to access your ice axe without removing the pack. The Cirque supports both diagonal and A-frame ski carry and includes a SwingArm strap system that allows the pack to move with you, enabling unrestricted climbing movements.
