The mat is super comfortable to practice and slips with me not at all, (and I sweat a lot on their hands) holding it liable and everything was wonderful, expands non-simply super. I have a slightly bruised knees and knees on the mat is me in spite of their "thin" pleasant and goes smoothly.
A cheaper and totally recommendable products.
I am totally satisfied with the product and will soon appoint a second piece for my friend.
