Do NOT buy from carscover.com
Instead of boring you with a long story, let me just say that they do NOT honor their warranty obligations. I have a truck cover that is a year and half old and it's self destructing. My truck sits under a shade cover and I live in So. California so there is no "extreme" conditions here. The company claims it has a three year warranty. They refused to honor this warranty and are completely apathetic to consumers complaints. Be warned.
