About Black Diamond Axiom 40 Pack

Black Diamond Axiom 40 Pack
Travel with all you gear using the Black Diamond Axiom 40 Pack. This is the perfect volume pack for going superlight while going on your trekking, hiking, or skiing adventure. Featuring the patent-pending reACTIV suspension, it lets you rotate your upper body naturally with your gait and reduce stress on the knees and ankles. Thanks to its shoulder straps and hipbelt, the load of your gear is distributed to more muscles groups, providing greater support and allows a more natural movement as you trek, hike, or ski. The suspension is also designed with an OpenAir backpanel and soft, breathable 3D mesh (on the hipbelt and shoulder straps) for ventilation. The Axiom 40 Pack has plenty of storage space to offer, including a top-loading roll-top closure, a removable top pocket, side stretch pockets, and a front compression stretch pocket. When you're done using your ski/trekking poles or ice axe, you can simply attach them to the pack's trekking pole/ice axe loops. Explore the outdoors with better movement and comfort. Opt for the amazing Black Diamond Axiom 40 Pack.

This product can only be shipped to U.S. addresses.
