FIR Infrared Heat 12 Volt Car, Boat, RV Heated Seat Pad
This 12 volt heating pad plugs into your vehicle's cigarette lighter. The heating element is made of Carbon Fiber Stitching in a honeycomb pattern rather than 1 continuous wire zigzagging through the pad such as all other heated pads and blankets.
