The best car cover solution for me is actually using both a Noah and a Weathershield. If my car has to be outdoors any time of year, I always use them. The Weathershield blocks rain, dirt, sunlight,etc while the Noah blocks whatever got past the Weathershield and ensures the car is totally dry without trapping moisture. It's also heavier and thicker to provide extra weight for stability and protective padding. In high winds I use use a bungee cord through the loops, no problems. I love that the Weathershield is machine washable at home too :up
