Osprey's Mutant 38 is loaded with technical features designed specifically for ski mountaineers and ice climbers. Aluminum stays and an inner framesheet create a lightweight suspension system that handles loads up to 50 pounds. The mesh Airscape backpanel and padded shoulder harness system ensure ventilation and all-day carrying comfort.
When the summit is in sight and every ounce counts, shed weight by removing the pack's suspension, rope and side compression straps and the helmet carry sling. You can also strip the pack's top lid and rely on the integrated FlapJacket to protect your gear from the elements during the final push.
Other alpine-specific features include A-frame ski carry loops, dual ToolLocks with bungee tool tie-offs, front panel webbing loops for crampon attachment. Glove- friendly zipper pulls and buckles keep your hands protected while grabbing gear. The padded hipbelt features a unique reverse wrap system to facilitate wearing a climbing harness while maintaining load stability. It also has built-in gear loops if you are traveling on easy ground but need to keep a few pieces of gear handy to build a quick rappel anchor on the way back down to base camp.

Osprey Mutant 38L BackpackBy: Marcus on 4 April 2019I have only used this backpack for a weekend but am already impressed with it's extremely intuitive design and versatility. It is a champion for it's price range and there is no surprise that it has won the Outdoor Gear Lab climbing pack of the year two years running. I bought it on the recommendation on someone who has used it for over 60 nights of long distance walking in Tasmania, Kakadu, multi-day scrub bashing in the Budawangs, and mixed mountaineering in the Darrens in NZ, and it is still in great nick. For my purposes I'm very impressed by both it's ability to shoulder and distribute heavy loads and the ability to strip out the frame, padding and the lid to drop it down to around 800g which puts it in the ultralight range. THe flapjacket second lid serves to highlight how well thought out the design is throughout. For trips when you aren't utilising the ice axe gear clips you should find the internal hole in the base cavity of the pack and remove them as they can create a slight rub zone and then you can easily put them back on when needed. Overall I'm extremely impressed and Ospreys great record for quality customer service and strong gear guarantees is a nice bonus.
