Input:
This is a great yoga mat! It's material is just enough cushion and "dense" without being heavy... so it looks to be super durable and won't easily fall apart.  It comes with a factory coating that I wasn't expecting, so the first time I used it in my hot yoga class, there was some sliding, but when I got home I just took a rough side of a (slightly soapy) damp sponge and lightly scrubbed it off... it was just fine for the next class and gets better with every class I take! Really is a great mat, & well worth the price! :o)
