Waterproof and warm gloves made with GORE-TEX material. - Brand: Arc'teryx - Materials: Genuine leather, GORE-TEX, Primaloft - Features: Waterproof, insulated - Design: Five-finger - Colors: Black, Gray Thank you for viewing. Used only in winter mountains. Even in the severe cold of the Northern Alps at minus 20 degrees Celsius, my fingertips didn't get cold and stop working. I also use a separate fleece inner glove, but that was only good to about minus 10 degrees Celsius. (I almost got frostbite.)
