The Osprey Mutant is a groundbreaking alpine climbing pack. This pack hauls heavy loads that larger backpacks can't handle, and then it mutates into a summit machine, climbing technical rock and ice with ease. This was an obvious pick for our Editors' Choice Award, as it excels in all of our testing metrics—and is among the more affordable packs in this review to top it all off. At only 38 liters, we thought this would limit the range of this pack—but we were able to load it up for 4-5 day trips with lightweight summer climbing gear. Osprey nailed it with thoughtful features on the Mutant, making this pack more simple and streamlined than their other packs.
