The Black Diamond Cirque 35L Backpack is a lightweight, technical ski mountaineering pack designed for fast alpine missions and demanding backcountry terrain. Built for big ski lines from Alaska’s Chugach Mountains to the steep couloirs of Chamonix, the Cirque 35 offers a clean, streamlined design with the capacity and durability needed for serious ski touring and alpine climbing objectives.

A roll-top main compartment provides expandable storage and weather protection, while an externally accessible avalanche safety pocket keeps essential rescue gear organized and ready when every second counts. A convenient quick-access side pocket allows you to stash climbing skins, ski crampons, or other critical gear without slowing down transitions.

The Cirque 35 features both A-frame and diagonal ski carry systems, allowing efficient gear management whether you’re booting up steep terrain or transitioning quickly between climbing and skiing. A padded waist belt and stretch-woven shoulder straps deliver comfort and stability during long approaches and technical ascents.

For steep alpine terrain, Black Diamond’s PickPocket™ ice axe carry system allows quick deployment of piolets or technical tools when conditions demand it.

Designed for serious backcountry skiers, ski mountaineers, and alpine climbers, the Black Diamond Cirque 35L combines lightweight performance with smart mountain-ready features.
