There are many organic/health stores in the US. I suggest you an online store called www.organicauthority.com that sells eco-friendly Yoga-mat which is the only eco-friendly sticky mat that contains only natural ingredients of jute (a plant), and natural rubber, which is tapped from trees like maple syrup. This natural fiber yoga mat does not contain any synthetic chemicals. Its pure rubber underside grips the floor and jute fabric/rubber mix on top allows you to stay connected with the Earth.
