Like its little brother, the Mutant 52 is loaded with all the options of a specialised winter backpack together with quite a lot of device holders, haul loops, ski straps, daisy chains, compression straps, and glove-friendly buckles. In the event you head into the backcountry regularly in winter, it truly is value your whereas to get a backpack optimized for winter use. It makes life a lot simpler when you should use the fitting device for the job.

Backpack Storage and Group
The Mutant 52 is a streamlined top-loading backpack with a floating prime lid and a most important compartment that closes with a drawstring. Whereas there are wand pockets on each side of the pack, the pack lacks aspect water bottle pockets or a entrance stuff pocket, in keeping with its minimalist winter character. Whereas the dearth of exterior storage pockets makes the pack extra sturdy for hauling up cliffs, there isn’t a scarcity of locations on the pack to connect cumbersome gear with sharp factors. Since path situations can differ extensively in winter, you usually want to hold a number of traction or flotation choices since you don’t know what you’ll encounter. In contrast to a three-season backpack, you’ll be able to’t retailer most of this gear (crampons, ice axe, snowshoes, microspikes) contained in the pack as a result of it’ll make every thing moist and rip it to shreds.
The floating prime lid is hooked up to the highest of the pack with plastic buckles and webbing straps, making it straightforward to take away if it’s not wanted. Floating lids are an incredible choice on winter packs as a result of you’ll be able to sandwich cumbersome gear like ropes, tent our bodies, or foam pads between the lid and the principle compartment if it is advisable to carry further gear on strategy hikes.
In the event you plan to make use of the Mutant 52 for backpacking, be sure you have a tent, tarp, or bivy sack that packs up small or that you may strap below the floating lid. The 52 liter quantity is on the small aspect for a winter backpack, which makes exterior gear storage and the usage of extremely compressible gear paramount.
The highest lid has two pockets. A cavernous, zippered most important pocket (with a key fob) that’s large enough to retailer a number of pairs of gloves, hats, maps, and navigation gear. There’s additionally a second smaller pocket that accommodates a helmet carry web with nook hooks that may be hooked up to the highest of the lid (if used) or hooked up to the daisy chains on the entrance of the pack. This small pocket can be massive sufficient to carry a GPS or satellite tv for pc messenger, smartphone, or digital camera and is a helpful place to stash stuff.
In the event you don’t want the highest lid or wish to scale back the burden of the pack you’ll be able to take away it and save near a half pound of drugs weight. The Mutant 52 comes with a completely hooked up pace lid (Osprey calls these flap jackets) that covers the opening over the principle compartment if the highest lid is eliminated and clips into the identical set of straps. A rope strap will also be used to safe coils or rope or different gear on prime of the flap jacket with or with out the floating lid. Personally, I discover a prime pocket indispensable in winter for spare gloves, hats, and map storage so I choose to maintain the floating lid hooked up.
The principle compartment has a hydration pocket inside with a hook to hold a bladder and twin hydration ports positioned between the shoulder pads. There’s additionally an inside body pocket contained in the pack with a detachable body (a plastic sheet and w/ 2 aluminum stays) which you may substitute with a bivy pad, though it’ll scale back the pack’s load-carrying capability.
Compression and Exterior Attachment Factors
The Mutant 52 has two tiers of aspect compression webbing straps, which will also be used to safe gear to the perimeters of the pack. Each shut with glove-compatible buckles. The underside buckle is new on this model of the Mutant 52. The earlier mannequin didn’t have it and it makes strapping snowshoes to the perimeters of the pack a lot simpler. As compared, many three-season packs have changed aspect webbing straps with cords, ostensibly to avoid wasting weight, however it makes their packs a lot much less appropriate for winter use as a result of the lineloc tensioners used to drag the aspect cords jam with ice, the cords take in water and freeze, and they’re unusable whereas carrying gloves.
There are strengthened ski loops positioned below the underside compression strap, making it attainable to configure an A-Body ski carry collectively aspect compression straps. There are additionally shallow wand pockets on the pack sides that will also be used to carry tent poles in place below the compression straps.
The Mutant comes with a common ice device holder system, together with two shaft holders. A pair of daisy chains and webbing straps on the pack’s entrance allows you to connect a pair of crampons with out a crampon bag. Alternatively, you’ll be able to connect a helmet right here or on the highest of the floating lid which additionally has daisy chains obtainable for that objective. The Mutant’s climbing and mountaineering pedigree are additionally evidenced by a three-point haul system, good for winching gear up cliffs and to portaledges.
Backpack Body and Suspension
The Mutant 52 is an inside body backpack with a stiff plastic sheet and two detachable aluminum body stays, so you’ll be able to alter the diploma of stiffness you need. The aluminum stays will also be custom-shaped to suit your physique form if desired. The pack additionally has load lifters, that are significantly helpful on packs designed to haul heavy gear. All the body system is detachable if you wish to save gear weight. Tightly packed gear can usually compensate for the dearth of a body, not less than by way of pack bag stiffness, or you’ll be able to drop a foam pad into the principle compartment and pack your gear inside it (like a donut) to create the identical impact.
The shoulder pads, again of the pack, and hip belt wings are flippantly padded with foam and supply minimal cushioning to assist hold the pack weight down. The shoulder pads are minimally outfitted with two hydration hose keeper loops and an adjustable sternum strap with a daisy chain height-adjustment system. The latter is helpful for attaching exterior pockets to the shoulder straps. Gone is the froth bivy pad in earlier variations, so I wish to insert a cut-down foam Zlite pad behind the shoulder straps (in the principle compartment) for emergencies and to additional insulate my again from the new water bottles I carry in winter.
The hip belt comes with gear loops as a substitute of pockets to rack gear with carabiners. It will also be folded again across the entrance of the pack if you happen to’re carrying a climbing harness. The hip belt closes with a single beefy buckle, utilizing pull-forward straps for mechanical benefit. The middle buckle can be glove appropriate and enormous, so it received’t jam up with snow, which is a giant drawback on packs that use small buckles. Gone are also the hip belt management straps of the earlier mannequin, which on stability is an organizational enchancment as a result of it reduces the variety of straps on the pack.
Extra Really helpful Winter Backpacks
The Osprey Mutant 52 is a light-weight inside body winter backpack optimized for climbing, backcountry snowboarding, and streamlined winter backpacking use. Weighing simply over 3 lbs, this 52-liter quantity is on the small aspect if it is advisable to pack a winter tent and cold-weather sleeping bag, though fairly doable if you happen to’ve refined your winter gear checklist to be as compact as attainable. Strippable parts allow you to considerably scale back the pack weight if that’s essential, albeit with some lack of performance. Whereas the Mutant 52 has an excellent exterior attachment system, the pack’s body and load-carrying capabilities are the place it actually shines. The mixture plastic body sheet and pair of aluminum stays make it attainable to hold 40-pound masses with ease, whereas the minimal shoulder strap and hip belt padding make the pack extremely responsive when snowboarding, climbing, and snowshoeing. It is a actually wonderful winter backpack.
