More functional than ever, the Ascensionist Pack 35L is the Goldilocks of alpine climbing packs—big enough to get you into the mountains, yet small enough to climb with.
We do our best to process and ship orders within 1-2 business days (Monday-Friday, excluding holidays). We kindly ask that you choose standard shipping where possible to reduce our environmental impact.

Unsure of the right 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.
