Take the legendary warmth of the Tundra split-finger gloves, add our 3-level heating system and you get some of the warmest, most comfortable gloves ever to fight the cold. This design uses a 1-3 split with your index finger free from the other three, providing better control and feel on the handlebars while providing excellent warmth. The heating filaments are durable and long lasting, powered by lithium-polymer batteries to ensure consistent warmth. The heating element covers your backhand and wraps the fingertips, providing full hand heat when used with heated grips on a snowmobile.
