Warm N Safe Heated Jacket Liners are trusted worldwide for their superior comfort and heating performance. These great motorcycle jackets are perfect for riding in colder weather conditions and can be worn as a stand alone or under a protective jacket. These 12V Heated Jacket Liners include a battery harness for a direct power connection to your motorcycle.This Women's Heated Liner Jacket produces 90 Watts of heat with a draw of 7.5A at 12.8v. Believe it or not there are those that do not realize that the motorcycle or ATV when running actually can put our up to 15.25Volts. That means the liner will actually produce more heat with the vehicle running than with the engine turned off. You will see us sometimes using 12.8V and sometimes 13.8V in talking about the Watts of heat and the Amps of draw. Don't get confused, it is just a base line for reference. So if you are going to test our heated gear, do so with the engine running to get the right Voltage and Amps to simulate being on the road.Product Description: Battery Harness Included Temperature Controller Sold Separately New Waterproof & Breathable Heated Liner using Gelanots! 110 Watts at 13.8V of Heat using our NEW Soft Heat Pure Science Heating Method Reflective "Illuminite" to keep safe at night when wearing it as a jacket (See Photo) Waterproof Breathable Gelanots Stretch Panels on the outside to keep heat against the body Anti-bacterial Stretch Panels on the inside to keep heat against the body Locker Hang Loop and Chest Pocket Pocket in Pocket Designed for to take the Remote Heat-troller Single or Dual Controller Functionality Tall Size is 2 inches (50mm) Longer Body, 1.5 inch (35mm) Longer Sleeves All Our Heated Gear should be used with an optional Heat-troller Breathable Shells with Wind Stop and Moisture Block Locker Hang Loop Pocket in Pocket Designed for to take the Remote Heat-troller Single or Dual Controller Functionality Tall Size is 2 inches (50mm) Longer Body, 1.5 inch (35mm) Longer Sleeves All Our Heated Gear should be used with an optional Heat-troller About Warm & Safe Liners: Form fitting, snug fit for maximum heat transfer Flex panels for maximum range of movement Heated pads on front, upper and lower back, sleeves and collar for full heat coverage Integrated glove plugs and pant plugs stow in zippered pockets when not in use Coaxial plugs engineered for best possible connection Dual Zone Heating Warm & Safe Heated Liner Q & A:Q.

Warm & Safe Heated Liners are designed to be temperature neutral. As you ride through warm and cold zones you won't have to stop by the side of the road to dress and undress. When not turned on, our liner is not going to get as warm as others and it is designed that way.Q. Do Warm & Safe liners have a comfortable fit?A. Lycra stretch panels allow a form fitting close fit to the body without sacrificing comfort, and allow optimum heat transfer to the body.
