Osprey Mutant Nimsdai 90

The Mutant Nimsdai 90 was created for Nepalese mountaineer and Osprey Ambassador Nirmal “Nims” Purja MBE and his team for their historic winter ascent of K2. Even in the most favorable summer climbing conditions, K2 has earned the reputation as the “Savage Mountain” and at 8,611 meters (28,251 feet), remained the only 8000-meter peak unclimbed during the winter season. In 2020, Nimsdai and his team became the first ever to summit K2 in the winter.

Tested in the harshest environment on one of the world’s toughest mountaineering objectives, the Mutant Nimsdai 90 is built to handle superior load carry in a streamlined pack that delivers stability when it matters most. A narrow profile, close-to-body carry and Osprey’s superior fit makes for efficient and ultimately safer movement in the mountains.
