I use these as a back pad in the gym sauna and sit on a towel. Works great. I hate gym germs. We throw them in the wash and hang dry. I recommend. Great price and functionality. They are a little thin so I have to be careful not to grab them with my nails and tear them. I hope you keep providing them. They are perfect for my use.

I've tried it out in the sauna and the steam room about 3 times now for an hour session each time. So far so good. I don't know why I expected the material to be harder plastic, but it's actually good as is.
