I've had these for a while, but haven't used them. The fabric on the surface of the thumb has deteriorated. The functionality is perfect, and the inner lining makes them very warm. These are three-finger mittens made of leather and synthetic fibers, with a fleece lining for excellent insulation. If you're interested, please contact me first! - Brand: Black Diamond - Type: Three-finger mittens - Material: Leather and synthetic fibers - Size: Men's L - Inner material: Fleece lining - Features: Adjustable strap Would you like them?
