The Shafer Canyon Pant is insulated using an Omni-Heat? thermal reflective lining that traps heat and omits warmth towards the body. This lining allows these waterproof trousers to be as lightweight as they can be. With 2-way comfort stretch fabric and other features like a built-in gaiter and snap gusset you will be able to confidently perform at your best on the ski slopes.
