This mat is excellent in theory- PVC free and environmentally stable. Sadly, however, that is about all it provides. Bulky set aside, the mat is slippery. My wrists have been soar due to the way I have to hold myself in downward dog seeing as there is little to no traction, and my hands slowly slide up the mat. As I slip, the mat scrunches and shifts in position instead of laying still on the floor. I am very unhappy with this mat, and would highly discourage purchashing it. I feel that I am slowly developing a wrist injury due to using this mat, which is unfortunate, seeing as I have a daily practice and had planned to use this mat for the next year to year and a half.
