Youve been in the pouring rain for three days straight, but all of your gear is nice and dry in the waterproof Arcteryx Naos 55 Backpack. Arcteryx made this revolutionary pack using seam-taped VaporTight fabric and gave it a roll-top closure to completely seal out any moisture. Its two front pockets and lid have water-tight zippers to protect your headlamp, map, and other small necessities. Arcteryx outfitted the Naos 55 pack with two aluminum stays to support your load and pre-formed shoulder straps for amazing comfort. Its pre-formed waist-belt attaches to a pivoting Load Transfer Disk which eliminates hot spots. And all of this weighs only 4lb 10oz. Available for US shipment only.
