Designed by guides and athletes, the Mutant 38 fits perfectly between its bigger and smaller siblings; great for long days in the mountains that dont require setting up basecamp but might require a ledge-bound shiver-bivy. The backpanel sheds snow and easy-to-use ice tool attachment and glove-friendly buckles mean less time fiddling with your pack. With a hipbelt that includes gear loops and stashes behind the pack to provide access to your harness when you need it, plus integrated helmet and rope carry, the Mutant 38 is a nimble and capable alpine machine that fits better and feels more comfortable than what youre used to. Whether youre enjoying a North Cascades classic or getting showered by spindrift in the Canadian Rockies, the Mutant 38 can do everything you need except belay you on the next pitch.
