This is the car seat cover that keeps one cool and comfortable regardless of the temperature outside. A built-in fan with two speeds circulates cooling air over the entire surface of the cover. Made from a material that is rugged yet soft against the skin, in evaluations by The Hammacher Schlemmer Institute it proved to be the most comfortable and the easiest to use. It can also heat a car’s seat; in tests, it produced the highest and most consistent warmth. With gentle vibration massage, removable lumbar cushion, and non-slip backing. Attaches with hook-and-loop fasteners, has a tethered remote, and is powered via 12V adapter or AC. 48" L x 21" W x 3" D. (4 1/2 lbs.)
