Great for short adventures or week-long outdoor excursions, the Osprey Mutant 38 Backpack covers them both with ease. Made with Armourlite 420D and Armourguard 900D, the Mutant 38 is strong and lightweight, and will stand up to anything Mother Nature throws at it. Equipped with thermoformed EVA foam, this Osprey backpack offers superior ventilation and minimizes moisture absorption, and a removable framesheet helps stabilize it when it’s full of gear. The Mutant 38 also comes with a 3-Point Haul System that allows secure wall hauling, as well as Reverse Wrap ErgoPull Hipbelt that secures out of the way when you’re wearing a climbing harness. It retails for around $149. Osprey.
