Harley-Davidson® Women's Heated BTC 12V Quilted Jacket Liner, 98320-17VW. The built-in temperature controller (BTC) offers three heat settings and five panels to keep your upper body wrapped in warmth. For a double kick of style and comfort, our custom Bar & Shield logo quilted pattern lines this lightweight, bulk-free layer. A simple connection to your bike's 12V electrical system powers this women's heated jacket liner. We also jacked up the versatility by designing a compatible heated gauntlet glove. The jacket's BTC also controls the gloves so you have only one temperature controller to manage. 100% nylon with quilted 3M™ Thinsulate™ Insulation.
