No subject to promotional offersThe Mutant 52 Blue Flame is an alpine climbing pack from the brand Osprey.
In this new generation of Mutant, Osprey's alpine range is modernised with even more robust and practical packs for your mountain outings.
The Mutant 52 is the largest volume version in the range, ideal for multi-day mountain trips. Despite its 52L, it offers good freedom of movement when climbing and remains comfortable even when fully loaded.
Its construction is meticulous with durable materials and it features all the accessories you will need, including a large, very practical top opening, an internal compression strap that can also secure a rope, a mesh pocket for your personal items, an internal sleeve compatible with hydration systems, and finally a ski carry system.
With its removable top pocket, the Mutant 52 allows you to adjust its volume depending on the outing, but also to keep your belongings with you in a mountain hut.
Well-equipped and developed with quality materials, the Mutant 52 will be the ideal partner to accompany you in the mountains all year round.
