Gerbing Gyde heated gloves are paired with our patented Microwire heat technology and made from lightweight, stretchable materials that help to improve dexterity and comfort during a wide range of activities. Finished with a water-resistant membrane, they repel water and keep your hands dry in adverse conditions. Small reinforcement layers are added to the fingertips for extra grip and added abrasion resistance.
