Patagonia Ascensionist Pack 40L

When does less equal more? When Patagonia decide to make a true alpine backpack. Weighing just 700g, The Patagonia Ascensionist Pack 40L is a lightweight, uncomplicated alpine and mountaineering backpack for all climbers seeking maximum efficiency and versatility at minimum weight. It features one large main compartment with a clam-lid closure and an integrated, asymmetrical spindrift collar to utilise every millimetre of the pack's volume and to fully protect against wet weather. Ergonomic shoulder straps (with load lifters) provide all-day comfort under heavy loads, and a lightly padded hip belt and low-profile sternum strap distribute weight evenly across the body. Two zippered compartments, one on the outside and another small pouch on the inside, provide quick access to important items and protect valuables. Side compression straps secure skis to the pack, two ice axe holders fit all sizes and shapes of ice tools, and exterior daisy chains allow for lashing of a rope, helmet, and any other items of gear.

Simple, minimalist, light: the Patagonia Ascensionist Pack 40L is designed for the true alpine essentialist seeking the fastest, most efficient ascent possible, with a lightweight yet durable pack.

Ripstop fabrics are made by weaving a nylon thread in interlocking, square patterns through a base material. (You can spot its distinguishable appearance in fabrics with a raised box or diamond pattern.) As a result, rips and tears, unable to bypass this nylon barrier, are confined to one very small area and will not spread throughout the fabric.

Ascensionist Pack 40L


Originating as a textile manufacturer of backpacks, boots, and apparel 50 years ago for the US Military - who still use them today - CORDURA® fabrics are highly durable, hard-wearing materials designed to keep soldiers protected within extreme and hazardous environments for months on end. CORDURA® fabrics are now regularly used in the outdoor industry due to their proven status as one of the toughest materials on the planet.
