I'm usually not too picky about yoga mats, but this one floats my boat. It's durable, uniquely functional with it's alignment marks, and beautiful to look at. I respect the care put into it's design by it's maker, James Armitage, and I have the highest admiration for his intentions and daring in bringing this unique creation to the world. I recommend it. It's a great mat to explore the grand possibilities of yoga on.
