Patagonia Ascensionist 55L climbing and mountaineering backpack

The Ascensionist Pack 55L from Patagonia is the high-capacity mountaineering backpack designed for multi-day expeditions and to tackle the most severe conditions in the mountains. The true strength of this backpack lies in its extreme modularity: the support frame, hip belt, and padding are completely removable to adjust the weight and volume of the backpack to the specific needs of the ascent. The top drawstring closure, designed for quick use even with gloves, is paired with side compression straps and multiple external attachment points that allow for stable and secure fastening of skis, ropes, and other gear. A dedicated and adjustable system allows for the transport of two ice axes, while the large top pocket ensures quick access to essential items. With a capacity of 55 liters, this backpack offers all the space needed for longer adventures without sacrificing the lightness and functionality required for technical mountaineering. Its structure is entirely made from high-performance recycled materials, including a 210-denier recycled nylon ripstop body with a TPU backing, which provides exceptional abrasion resistance and a DWR water-repellent treatment to protect the gear. The production in a Fair Trade Certified™ facility demonstrates a commitment to an ethical supply chain.
