The Arc’teryx Alpha FL 30 is a stripped down pack created for climbers who want a light yet durable and highly weather resistant pack with no unnecessary straps or parts. Instead of a traditional top lid, the Alpha features a RollTop closure, with a small external pocket, which extends the packs volume as well as providing a waterproof seal and easy access on the go. External lash points can be used to attach tools, crampons, extra layers, helmets, sleeping pads, etc. This pack has everything you need and nothing more, a no nonsense pack ideal for winter or summer climbing and urban cycling.
