I use this towel on top of my cheap Target yoga mat to soak up sweat and provide more traction, and it works perfectly. Since it's coated with rubber on the bottom, it doesn't slide (unless, of course, your mat is wet before you lay the towel on top of it) and it's heavy enough where it stays put (it doesn't get all crumpled up when you move your feet, like the Yogitoes towels are notorious for). This towel is a little pricey (albeit just a fraction of the cost of its competitors) but definitely worth the investment. It makes a world of a difference compared to using just* a mat, especially during hot yoga.Care instructions: throw in washing machine on cold, hang dry. Only takes a couple hours to dry. I've done this a couple times now and it's still like new!
