Constructed from strong ripstop nylon with zoned reinforcements, it blends an advanced feature set with our new Air Contour carry system for serious all-mountain performance. The comfort, fit and stability are outstanding, thanks to an adjustable back, a one-piece scapula - which runs on internal aluminium rails for superior load transfer - and a variety of compression straps and tensioners. A soft polyurethane sponge lumbar with softer foams in the hip belt and harness gives instant comfort without compromising stability and the back panel mesh is slightly trampolined away from the moulding to aid breathability and airflow.

Perfect for easy access to you kit when bivvying for travelling hut-to-hut, it features a wraparound front zip which enables you to open it like a duffle bag. With secure attachment points for an axe and walking poles, plus daisy chain lashing points, stretch mesh side pockets and a large front-stash pocket that’s perfect for a waterproof shell, the Cholatse 52:57 is the ideal year-round pack for mixed, multi-day mountain adventures.
