Arc’teryx Alpha FL 20 Backpack mountaineering backpack* Mountaineering

The Arc’teryx Alpha FL 20 Backpack mountaineering backpack is designed for those who achieve more with less. Ideal for minimalist climbs and summit pushes, it’s crafted from Hadron AC² LCP (Liquid Crystal Polymer) grid fabric for exceptional durability and weather resistance at minimal weight. Lightly padded shoulder straps and a laminated back panel enhance carrying comfort, while the external bungee system compresses the load and secures crampons or a parka. A top strap holds your rope, and dual dog bones keep your ice tools in place.
