Mutant Nimsdai 90

No mountaineering pack has been tested quite like Osprey’s new limited edition Mutant Nimsdai 90.

Designed together with Nepalese elite mountaineer and Osprey Ambassador Nirmal Purja MBE (Nimsdai) - the fastest person to climb all 14 of the world’s 8,000m+ peaks, and the first to summit K2 in winter without oxygen - the Mutant Nimsdai 90 is built to meet all the demands of high-altitude mountaineering.

Nirmal Purja, Elite Mountaineer and Osprey Ambassador:

“Since Project Possible, I have always had Osprey on my back. High altitude mountaineering requires skill and a strong reliance on kit; my pack needs to comfortably support significant weight, carry critical equipment securely and perform in the most gruelling of terrains. It is, for this reason, I am proud of what we have created with the Mutant Nimsdai 90 – it’s THE ultimate workhorse backpack, able to withstand every challenge.”

Adam Alder-Cox, Product Line Manager, Osprey Europe:

“Nims is the dream of a product development team - he knows exactly what he needs and wants in a pack. Together we’ve designed the Mutant Nimsdai 90 to be the best of the best in terms of fit, comfort, durability, features and performance.”
