Osprey Packs Mutant 38 Backpack - A sleek option for ice climbing, fast-and-light alpinism, or ski mountaineering, the lidded Osprey Mutant 38 offers over 2100 cubic inches of storage capacity and an abundance of climb-friendly features at a minimal weight. An aluminum support stay and a 1.2mm HDPE framesheet lend the pack lightweight structure and load-balancing stability. When you aren’t carrying as much weight or want to reduce the weight of the pack itself, you can remove both of those entirely. A spacer mesh backpanel cushions the load while offering breathability to help keep you cool. Padded shoulder straps enhance fit and load-hauling capability, as does a contoured hipbelt that can easily be pulled back and lashed against the pack itself for ease of use when you’re wearing a climbing harness. Load-lifter straps and an adjustable sternum strap further ensure a proper fit. The Small/Medium Mutant 38 accommodates torso lengths ranging from 15”-19” and the Medium/Large best fits 18”-22” torso lengths. The top-accessed main packbag has a protective lid that can be removed entirely to reduce the weight of the pack. Dual compartments in the lid aid in gear storage and organization. An integrated FlapJacket panel pulls forward to protect the packbag if and when you choose to leave the lid behind. There are also an abundance of climbing and alpine features like reinforced A-frame carry ski loops, glove-friendly zipper pulls, dual ToolLocks with bungee tie-offs, front panel crampon attachment loops, and a removable helmet carry system. Other features include side compression straps, gear attachment points, a sternum strap safety-whistle, and a lined sleeve that makes the pack hydration system (sold separately) compatible. Designed to make the summit attempt all the more likely, the Osprey Mutant 38 Backpack comes equipped with everything you need above the tree line.
