We are excited to offer eco friendly natural rubber Jade Yoga mats and towels made in the USA. These yoga mats are made without PVC or synthetic rubber. The Harmony yoga mat is considered to be one of the best on the market. Sustainably better for the earth, the natural rubber is tapped (much like maple syrup) from renewable rubber trees. Natural rubber has better grip and cushioning. In partnership with Trees for the Future, a tree is planted with each Jade Yoga purchase. All Jade Yoga products include free shipping in the continental USA.
