Arcteryx made the Silo 50 Backpack large enough to take on a weekend ski tour and versatile enough to carry everything whether you prefer AT gear of a splitboard. The front pocket keeps your shovel and probe easily available in case of an avalanche. Arcteryx gave the Silo 50 Backpack a roll-top design and side zipper to allow easy access even when your ride is strapped to your pack. Of course, this backcountry ski pack also includes a hydration sleeve to carry your bladder and keep water a sip away during your entire approach and descent. Only available for US shipment.
