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.
