These winter gloves are made entirely of 4-way stretch Neoprene material. Neoprene is known for its good thermal insulation. As soon as the inside of the glove is warmed up by your body heat, it will stay warm for longer periods. With wind and water blocking neoprene provides excellent protection against cold wind and moist. The hand palms are fitted with a non-skid coating for better grip. During the sport practice in the dark the reflective logos on your Neoprene Gloves will light up to increase your safety.
