Input:
This is an excellent mat for all purposes. I never need to double my mat, even with a knee injury. Some people have complained that it is too heavy to cart back and forth to class, but I think most yoga students are plenty strong enough to carry 6 pounds (especially if you get a shoulder strap or bag). When I go to class, I don't want to think about my mat. This one allows you to focus on your movement and breath, not on how much your mat is moving or isn't giving you enough cushion or support.
