Prana's Neo Natural Yoga Mat is eco friendly and luxuriously thick. It's made of cotton and natural rubber and is completely non toxic and biodegradable. It's a huge difference from the thin sticky mats, this stays in place, even on carpet. Very comfortable mat! It does off gas a rubber odor for the first few uses, but it is not toxic and will dissapate. I find it solid and supportive and think it's a great mat. Find it HERE.
Prana is having a big sale on their website at the moment, check them out HERE.
