Setting a standard for light, durable protection, the Alpha is made for confident travel in rugged, unpredictable alpine environments. Made with waterproof, windproof, breathable 3L GORE-TEX with our ultralight, ultra-durable Hadron' LCP (Liquid Crystal Polymer) grid face fabric, the Alpha's abrasion resistance rivals pants made with much heavier materials. The innovative waist cinch holds fast and rides easily under a harness or hipbelt, and full side zips make on-and-off easy.
