Arc'teryx Naos 70 Backpack - 4270-4640cu in

A week-long backpacking trip basically guarantees at least one day of rain. Don't worry—the waterproof Arc'teryx Naos 70 Backpack ensures your gear stays dry. Arc'teryx constructed this revolutionary pack with seam-taped waterproof VaporTight fabric and a roll-top closure to keep every drop of water from your gear. Water-tight zippers on the two front pockets and lid keep your smaller items dry, as well. The Naos 70 Backpack's Monoframe uses two aluminum stays for amazing support while its pre-formed shoulder straps and waist-belt provide unparalleled comfort. The pivoting Load Transfer Disc allows the waist-belt to flex with you and eliminates chafing during your week in the mountains. *Available for US shipment only.

Bottom Line: Welcome to the waterproof revolution of the Arc'teryx Naos 70 Backpack.

Think long term investment

By: Mountainrunner(3)

Expensive? Yeah, but this is an investment you cannot afford to miss out on. Arcteryx packs are rivaled by no one when it comes to comfort and suspension. The pack itself does run a little heavier than other packs --- but the suspension makes it a moot point. You do not fatigue from a poor fitting pack or a load that transfers all over your torso.... I've had that happen with other packs. You'll need to get used to a top loader if you have not used one -- but they force you to simplify and put thought into the way you pack. This pack is an all around winner. You cannot lose with it. It will run you some dough --- but you should have it forever.
