Patagonia Ascensionist 35L Pack

Our Take

Finding the perfect day pack for mountaineering is never easy; it's got to be big enough for all your gear, but small enough to climb with. Patagonia's Ascensionist 35L backpack just solved that problem. Packed with mountaineering specific features like an ice tool and rope carrying system, plus bluesign® approved DWR fabric, the Ascensionist is truly a Goldilocks of alpine climbing packs.
