Inspired by our ambassadors’ requests for a bigger climbing pack, the Ascensionist Pack 55L is a streamlined and ultrafunctional gear hauler designed for long approaches, lightweight expeditions and full-on missions into the alpine.
We do our best to process and ship orders within 1-2 business days (Monday-Friday, excluding holidays).

Returns and Repairs
Unsure of your size? Can’t decide between jackets? Our Customer Service team is here to help—the less unnecessary shipping, the better. We have no time limit on returns and accept both current and past-season products.
From May 5th 2021, you will no longer receive paperwork inside your Patagonia order. We are making this change to reduce the amount of paper we use. You can still find all of your order information, and an invoice, in the shipping email we send you. To return an item, please visit the instructions on our returns page.
