Osprey Argon 110 Backpack - 6700-7100cu in

Big trips call for lots of gear. The massive Osprey Argon 110 Backpack holds everything and supports the load when you hit the trail. Thanks to dual aluminum stays, a molded back panel, and a well-padded waist-belt, this Osprey pack easily handles loads up to 80lbs. There's plenty of space for everything thanks to a massive 6900cu inch cargo space (medium size), two front pockets, and a sleeping bag compartment. The Argon 110 Backpack also comes with an integrated hydration system to keep the water flowing on those hot days, and the removable lid converts into a lumbar pack when you want to take a short stroll from camp.
