The coldest winter day is no match with the Thermologic® Heated Gloves. These gloves allow you to control the temperature. Thermologic® technology’s key feature is its metal clad polymer fiber filaments woven into the glove lining. Traveling down each finger and back of the hand, the filaments produce ultimate in warmth. These filaments are generated by lithium ion batteries, housed in pockets on the back of the gauntlets.
