OSPREY Mutant 52

We learned everything we could from our guides and athletes to ensure that when you're heading to bigger ranges for more committing objectives that require extra gear, the Mutant 52 has everything you need for the approach to basecamp and the route ahead. The cavernous main compartment has a ton of room for gear and clothing, dual ice tool attachments, reinforced A-frame ski carry, and wand/picket pockets secure your toys and necessities to the exterior and for harder pitches a three-point haul system allows you to bring the pack up once you've established the belay. The hipbelt includes gear loops, and if you're moving light and fast and need access to your harness, the top lid and hipbelt are removable to save weight and space. Like every pack we make, the Mutant 52 is backed by our All Mighty Guarantee. For big climbs and long approaches, the Mutant 52 is the way to go. KEY ATTRIBUTES FORM FOLLOWS FUNCTION Built to be lightweight and reliable with alpine-specific features such as dual ToolLocks with bungee tie-offs, helmet carry (52L and 38L only), strippable features, rope carry and a narrow profile for efficiency in the mountains. STRIPPED WEIGHT Removable top lid (for 52L and 38L only), removable suspension (framesheet on 22L, framesheet and/or dual stays on 38L/52L), and a removable hipbelt on 52L allow the user to trim weight. FIT Osprey's superior fit makes for efficient and ultimately safer movement in the mountains so that you're never thinking about your pack during runout cruxes through rotten rock or thin ice.

To determine your torso measurement, please see diagram below. This measurement starts at the iliac crest, which is the top of your hipbone on the side of your body that acts like a shelf. From this point, measure to the C7 vertebra, the knobby bone at the base of your neck when you put your head down. Reference the torso length below to match the correct pack size. HARNESS SIZING Osprey Xenith, Xena, Aether, Ariel, Atmos and Aura packs offer interchangeable shoulder harnesses. Harness sizing usually corresponds to pack size. A properly fit harness should terminate 2" to 3" beneath the armpit when at the proper torso length. The webbing should not touch the side of the body below the padding. WOMEN'S SPECIFIC True function and comfort along with style. We have over 20 years of experience designing women's packs. PACK'S SHAPE The pack's shape is patterned to be more narrow and with added depth in the right places. This allows greater freedom of movement and increases stabilization by lowering the position of the load to a more optimal center of gravity. As a result, the load is more proportionately supported on the hips and along the structure of the back. HARNESS The shoulder harness is designed with thoughtful angle changes and varying padding thickness to create an anatomical fit for a woman's neck, shoulders and chest. This is balanced with optimizing where the tension from the pack's load is carried. For women, our sternum strap is a key piece in equalizing the pressure across the shoulder harness. The padding used is also specific in order to be more comfortable when carrying a heavy load. HIPBELT The hipbelt is designed with thoughtful angle changes and varying padding thickness to create an anatomical fit. The hipbelt is also narrower in height for better comfort so it doesn't dig into the ribs or upper thighs when scrambling or climbing. Most importantly, women's hips are more conically shaped with a larger difference between the waist and hip measurements. We sculpt and angle our hipbelts accordingly for comfortable load transfer and optimal support. Again, the padding used is also specific in order to be more comfortable when carrying a heavy load. MEN'S / UNISEX SIZING WOMEN'S / KID'S SIZING HIPBELT SIZING Osprey Xenith, Xena, Aether, Ariel and Variant series packs offer interchangeable hipbelts. To determine hipbelt size, measure around the hips, at the iliac crest, not the waist. The padded portion should wrap well around the hips, leaving a gap of 3" to 6" between the tips of both hip pads when securely tightened.
