There is no slipping, stretching or bunching up with this mat. Padding is perfect for my knees.
This seemed to have good reviews and was in the price range I was looking for, lucky me. I am impressed with the difference between this mat and the cheap ones.
I did recommend this yoga mat to friends in my yoga class, they touched the material and said it has a really nice top texture.
I loved the mat. Very large, sturdy and beautiful!
