I have bought or tried just about every yoga mat available. This is my hands down favorite...! It really is non-slip, even in hot class and cushions the knees really well. It's a beautiful thing. UPDATE: I have had two of these mats now. Still love the mat, but only for the first few months. It then starts to become like an elastic band. So when you are in down dog, your mat gets longer! I now have the Lululemon mat and feel like this is a long term keeper, not just for a few months.
