I got these to cover the vehicles while we are away in winter, so haven't properly put them on yet. However, they seem well made, well sewn, and I don't see any problem at all to use them when the time comes. I like that it reflects the light and will melt any snow that gathers, rather than letting it sit on the car. I could see even covering a car with these in stormy weather to protect from light hail or flying bits/sand. Good value for a well made product.
