Climb it all.
The Osprey Mutant 28 Backpack was designed and built for vertical endeavors of all disciplines, so climbing, mountaineering, ice climbing, and ski mountaineering objective will all be within your reach. The Mutant comes well equipped to deal with long and technical approaches, but can also be stripped down when you need to save weight when beating the weather means going light and fast. Being the smaller option in the Mutant line, the Mutant 28 has a large bucket-style zip opening with an internal slash pocket and a lightly padded hip belt with gear loops, making it the most minimal of Osprey's Mutant packs.
An aluminum stay and framesheet can both be removed when packing light, or can be left in when carrying loads up to forty pounds. The large main compartment swallows everything you need for single day objectives in the alpine and will carry either a skinny alpine cord or long sport climbing rope via the integrated rope compression strap and helmet carry net. The Mutant will also carry ice tools and skis when you're lured to the alpine to attempt some mid-winter ascents and descents. An integrated sleeve will carry a hydration bladder up to three liters in capacity, and all of the zippers are fitted with glove-friendly pulls for added convenience when you're trying to keep your fingers warm.
