Why We Like The Westalpen 3L Jacket

We utilize the versatile design of the Westalpen 3L Jacket for all of our high alpine excursions, from rock climbing to ski mountaineering and everything in between. The three-layer Toray Dermizax NX membrane offers top-tier waterproofing for the most intense storms and is complemented by a touch of merino wool insulation for added warmth. The jacket’s performance fit features longer sleeves and torso to help you maintain your mobility for tricky crux moves while wearing a harness.
