Black Diamond Cirque 45L Backpack
Black DiamondCirque 45L Backpack

Light on weight, heavy on capacity.

Despite being one of Black Diamond's lightest, the Cirque 45 Backpack boasts plenty of space for day-long backcountry tours and ski mountaineering missions. Designed for minimalists 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.

Although streamlined for minimalists, the Cirque still sports innovative technology that doesn't add a whole lot of weight to your kit. The SwingArm shoulder straps and stretch waist belt provide active suspension and a streamlined fit. The Cirque is compatible with Black Diamond's AvaLung and SilNylon lid pocket for added safety and capacity when traveling in avalanche terrain.

  • Familiarity: I've used it once or twice and have initial impressions

Bought this for ski touring and it's a very light pack. The sunglass pocket on the hip strap is pretty convenient. Although, I it's tough to also fit a hardcase for glasses inside of it. The side zip access pocket is a bit small, but better than only relying on top access. There aren't a lot of small pockets for organization, but there are enough.

Finally a great ski pack
