The Beginning - We sent out something like 500 samples and got nearly 300 phone calls - an incredible response. People had never seen anything like it and were thrilled to be able to get a yoga mat that actually gripped. In addition, natural rubber has better cushion and resilience, making it more comfortable. Finally, tapped from rubber trees, natural rubber is a renewable resource and our mats are made in the United States in compliance with U.S. environmental laws and contain no PVCs - making our mats the first "green" and non-toxic yoga mats. -JadeYoga
