This is great for anyone who has sweaty hands and feet and doesn't want to slide down their mat while doing yoga. You can throw it in a front-loader washing machine with some white vinegar and let it air dry to keep clean. It's great to bring traveling even if all you do is stretch out and take a nap. You can layer it over nasty gym mats if you don't have a thicker mat to put down for more padding. Mine first one disappeared at the gym and I bought the exact same product as a replacement because it's the best I've found!
