Experience unmatched warmth and comfort on your rides with the Synergy Pro-Plus 12V Heated Glove Liners. Crafted from 100% polyester, these liners feature wind and water-resistant soft-shell fabric on the top and a microfleece interior, ensuring your hands stay warm and dry. The use of Spandex in the palm and fourchettes minimizes bulk, enhancing your grip and control. These liners are equipped with flexible carbon fiber heating elements that extend to each fingertip, offering even warmth distribution. Safety and efficiency are prioritized with the use of thermoplastic elastomer wires. Easily adjust the heat with a built-in waterproof LED controller offering three settings to match your comfort needs. Connect them to your jacket or directly to your bike's battery for continuous warmth (note: Y-splitter required, battery harness not included). Keep your focus on the journey ahead, not the cold, with these hand-washable heated glove liners, designed for the avid rider seeking adventure in any weather.
