Enjoy unparalleled warmth and comfort during your rides with the Synergy Pro-Plus 12V Heated Glove Liners. Made from 100% polyester, these liners incorporate wind and water-resistant soft-shell fabric on the top and a microfleece lining inside, ensuring your hands are both warm and dry. Designed with Spandex in the palm and fourchettes, these liners reduce bulk to improve your grip and control. The liners are outfitted with flexible carbon fiber heating elements that reach every fingertip, providing uniform warmth. Safety and durability are enhanced with thermoplastic elastomer wires. Customize your heat level with the built-in waterproof LED controller, which has three settings to suit your comfort. Connect these liners to your jacket or directly to your bike's battery for consistent warmth (note: Y-splitter required, battery harness not included). These hand-washable liners are crafted for the dedicated rider who doesn’t let weather stop their adventures.
