I have purchased many Yoga mats different thicknesses and have never been happy with any of them. Lots of different issues ie:- no grip or to thick for balance poses. I recently purchased a 5mm reversible yoga mat from lululemon and am in love. It is awesome I wash it with warm soapy water and it cleans up as good as new. Thickness is perfect. My husband is happy I can stop wasting my money and doesn't understand there is a difference lol
