I have been looking at these for over a year and finally pulled the trigger since it's been a hot and humid summer of marathon training. My black/gray car seats certainly have appreciated the protection! The towel is really easy to use to cover my driver seat. I've also spread it across the backseat in an effort to prevent white dog hair from sticking to my seats when I have my pup along for a ride.
I have only used it once so far to change, but it was really helpful after a race where there was no place to change and I really wanted to get out of my sweaty clothes.
I love all of the color options. I went with the royal blue and it's a really great color. I think the towel is a good quality fabric and so far is holding up well to washings. I would definitely recommend it to my fellow runners, as well as anyone who enjoys the outdoors at any time of year.
