Osprey Mutant Nimsdai 90L Climbing Rucksack
All about this product
General
Designed in partnership with Nepalese mountaineer and Osprey Ambassador Nimsdai Purja MBE, the Mutant 90L Climbing Rucksack is ready to take on the harshest of environments while carrying a significant amount of kit, allowing you to move fast and efficiently in the mountains.
With the same features as you’d expect on the Mutant, such as an ice-tool holder, side ski carry loops and compression straps, keep everything secure. The snow-shedding back panel has a removable frame sheet, while the outer material is highly durable to endure even the roughest exploits and is made from recycled bluesign approved high tenacity nylon and PFC-free DWR treatment that sheds moisture.
