Firstgear's Ultimate Tour I-Touch Gloves are made from Grade A, top-grain, drum-dyed cowhide. The heated gloves include a thin layer of Thinsulate . Thinsulate keeps riders warm when it's cold outside. The unique microfibers or fine fibers that make up Thinsulate insulation work by trapping air molecules between skin and the outside. The more air a material traps in a given space, the better it insulates from the cold outside air. Insulation utilized by Firstgear® allows riders to feel the bike and not fatigue your hands. The inside of the gloves are made with a breathable waterproof membrane. The palms have reinforced protection. The fingers are pre-curved providing comfort the first time you put them on. The thumb has double heat, for increased comfort.
