I had never seen anything like this before, and I thought it was a pretty cool yoga mat to have. Quite a departure from the rectangular mats I usually see around.
The Mandala Yoga Mat is "the original 6-foot round mat". The creator wanted to get away from the confines of a rectangle and have a mat that facilitates freedom of movement in all directions without boundaries and restraint.
What do you think?
