I purchased a "Plushweave" from
http://www.calcarcover.com/how_to_select.aspx over 7 years ago, and today is it still as good as new. I keep my SPF covered 90% of the time when it is parked in the garage and used it outside dozens of times (once in the SNOW!). I've washed it maybe 3 or 4 times. I highly recommend it!
