Arcteryx Alpha fl 20L Unisex Climbing Backpack - Black
Our smallest Alpha FL pack. The one for those who do more with less. Sized for minimalist climbs and summit pushes, it’s made from our Hadron AC² LCP (Liquid Crystal Polymer) grid fabric to deliver outstanding durability and weather resistance for very little weight. Lightly padded shoulder straps and a laminated back panel improve carrying comfort, and the external bungee system compresses the load and holds crampons or a parka. A top strap secures your rope, and dual dog bones hold ice tools.
