Made with a three layer structure, this jacket is made to last. 3L Gore products tend to have extremely long service lives, and they give reliable weather protection. This C-Knit version of Gore-Tex is also extremely comfortable to wear, and breathes well. As a bonus, key areas at the upper back and hood boasts Gore-Tex Stretch for enhanced freedom of motion. Like other new Gore-Tex products, the Alpine is now made with the ePE membrane, meaning the product is not completely free of PTFE. Due to popular demand, the jacket also includes a walkie talkie pocket. It was left out of the pattern for a while, but as consumers criticized the change, Peak Performance brought it back. - Regular fit - Gore-Tex 3L C-Knit: waterproof, windproof, breathable - Tough Nylon surface fabric - Gore-Tex Stretch panel in upper back - 2-way YKK AquaGuard zipper - Detachable snow skirt, compatible with Peak Performance skiing trousers - Surface fabric made of tough polyamide - Recco avalanche reflector -
