Patagonia Ascensionist 40L Backpack

1 item left

The Patagonia Ascensionist 40L Backpack is a lightweight Ski Touring/Alpine Climbing technical pack. It features a rugged but lightweight design, aimed at fast ascents and minimalist multi-day missions.

40L volume is a great amount for an overnight hut trip with the capacity of daypack duties. 40L is a great in-between size if you split your time doing day and multi-day trips. If you need to carry crampons, a bivy sac and a bunch of rope, there is plenty of room in the Ascensionist 40L. The compression straps allow you to manage the load so it doesn't feel huge if you aren't filling it to capacity.

Fit wise the Ascensionist is a dream. With Ergonomic shoulder straps and lift loaders, the comfort is far from the minimalist design of the rest of the pack. Complete with a lightweight hip belt and low profile Sternum strap.

If you want to go far, the Ascensionist will take you there.
