A very comfortable liner made with an exceptionally soft and supple Lycra that contours to the hand. The design is simple but effective. The firm fitting stretch fabric allows for a snug fit as these gloves are designed to be worn under your regular gloves or mitts. A button on the glove allows the user to control the temperature setting. Utilises Gerbing’s European patent pending heating technology, the most efficient and durable heating technology ever developed. Heats entire length of each finger, including the thumb, as well as the back of the hand.
