After playing in the water (or even just sweating in the gym) it sucks to get your car seat wet, sandy, and sweaty! This is the perfect solution to that problem. A waterproofed seat towel that fits over the head rest and has elastic straps to hold it in place. It's easy to take it out of the car to shake it out, let it dry or wash it. And then when you run home after windsurfing to take a quick shower before your date....you don't have to worry about sitting back down in your wet and sandy car seat!
