For fast and light alpine missions.
The ultralight and highly weather-resistant Arc''teryx Alpha FL 45 Backpack is designed to help you move quickly through rugged terrain whether you''re on a light alpine mission, crushing ice and rock climbing, or putting in technical ski mountaineering lines.
Arc''teryx made the Alpha FL from lightweight but bomber ripstop fabrics to withstand the rigors of ice and granite without slowing you down. To keep your back and shoulders comfortable, the AC2 suspension system offers load support with minimal weight, while compression straps help you manage your load for better balance in tricky spots. The Alpha FL is also fitted with an expandable drawcord collar for additional capacity on a minimalist overnight trip. External attachment points can be used to hold skis or a sleeping pad, and a front panel bungee attachment stashes crampons or an extra layer so you don''t have to stop any unpack every time you move from flat ground to steep snow or ice. The webbing hip belt is lighter than padded belts and fits more comfortably under a harness, and thermoformed shoulder straps and a rigid formed backpanel provide support and structure while still offering a comfortable fit.
