The Volt Motorcycle 12v Heated Jacket Liner is the perfect riding accessory to help you stay warm and comfortable for those road trips with unpredictable weather conditions. The most important feature you need to know is that it is wired for two systems. This means that you can power your heated jacket on a separate heat setting (system 1) than your heated gloves (system 2). The 12v Heated Jacket Liner comes complete with a Dual Therm controller as well as a wiring fuse harness. Insulated to be thermally efficient along with being wind-resistant and highly compressible. The rip-stop coated nylon shell and form fit allows it be worn comfortably underneath your riding jacket with just a single layer underneath. Includes rib-knit on the cuffs and the waist and tall collar to help seal in the heat and keep out the cold. Other design features include screen print graphic on left chest, two handwarmer pockets and zippered power plug storage pockets to hide them away when not in use. The heating system includes multiple large insulated heating panels strategically located in the collar, chests, arms and the back that are designed to evenly distribute soothing warmth throughout your upper body.
