The set in my car is 3 years old, and still looks okay. These are great when you get into the car while you are still damp, but they do get really warm after you sit in 'em for awhile (neoprene after-all). They get REALLY warm after your car has been parked outside in the sun all day...
Great product, just doesn't "breath" too much. I would buy another pair.
