These mittens feature the Snow Stopper patented extra-long sleeve, waterproof Drypel liner, and 40g Thinsulate™ insulation. The nylon shell, unique to the SnowStoppers® Nylon mittens, resists snow and ice better than fleece. The tough grip palm is great for skiing/snowboarding, sledding and even building snowmen!
