text: The markings on this Mat are really helpful, it has just the right amount of padding, and I dont slip at all when I use it. It tends to stretch a little when I do poses that put a lot of force or tension in opposite directions, like downward dog, but it doesn't cause any problems. It's definitely bio-degradable. I can already see some slight wear and tear after using it daily for about a month. But that's the point of a mat like this. It's not going to exist forever in a landfill when I have to get rid of it and that's a relief.
