Whether you're climbing in challenging alpine conditions or spending long days tackling multi-pitch climbs, the Mutant 38 is tuned for vertical ice and steep terrain.
Developed with the help of local guides and athletes and refined through years of use in extreme conditions, its close-to-the-body fit and sophisticated feature set promote safety and stability in even the worst conditions.
With new colors, advanced materials and sophisticated features, the latest iteration of the Mutant 38 is even more formidable than its predecessor, proving that the evolution isn't over yet. The entire Mutant family benefits from the addition of lightweight recycled NanoFly and Robic fabrics, which provide impressive durability and a lower environmental impact than the original materials.
In winter, you'll appreciate the snow-free material, side loops for attaching skis, and a reversible system that allows for quick and secure axe attachment. If you have a harness, the hip belt can be fastened in reverse (on the front of the pack) or even removed completely.
The Mutant fifth generation climbing pack is a reliable and smart companion for all your climbs.
