Osprey Nimsdai Mutant 90

No mountaineering pack has been put to task quite like the Nimsdai Mutant 90. Created for Nepalese mountaineer Nirmal "Nims" Purja MBE and his team for their historic 2020 winter ascent of K2, one of the world's most demanding mountains, it pushes the limits of what an alpinist's pack is capable of. With the same attention to safety and comfort as the rest of the Mutant series and a massive capacity for gear, conquer the world's greatest peaks with superior fit, form and function. Osprey's commitment to performance doesn't compromise on sustainability—this pro-level pack is constructed with 100% bluesign® approved recycled fabrics, delivering excellent durability in a lightweight and low-impact package.
