The worst rainstorm hasnt a chance of getting a drop of water on your weekend backcountry gear, when you pack it in the 2690cu inch Arcteryx Naos 45. Seam-taped VaporTight fabric and a roll-top closure create a completely waterproof barrier. The two front compartments and lid utilize watertight zippers to keep the little stuff dry, as well. Arcteryx built the Naos 45 Backpack with pre-formed shoulder straps and a pre-formed waist-belt that pivots on a Load Transfer Disk to eliminate chafing while you hike. Top it off with two aluminum stays and an ultralight Monoframe back panel, and the Naos 45 is one amazing overnight backpack. Available for US shipment only.
