JADE HOLDS: As Jade is made with open cell, natural rubber, you can say goodbye to slipping on your practice mat - even if it gets wet with perspiration. Natural rubber has long been used where safety demands non-slip performance. Jade takes advantage of the non-slip properties of natural rubber- resulting in the best slip-resistance on the market. Try it - we"re sure you"ll agree. JADE PERFORMS: In addition to providing better slip-resistance, because it is made of natural rubber, Jade has exceptional resilience, unmatched "compression set" resistance and incomparable cushioning. These characteristics guarantee you the ideal mat for those looking for maximum comfort and performance. Jade can be hand washed with mild soap and warm water; hang or lay flat to dry (out of direct sunlight). JADE is GREEN: Jade is constructed of natural rubber, a renewable resource tapped from rubber trees - containing no PVC or ozone depleting substances. Perfect for the yogi concerned about the earth and is made in the USA in compliance with all U.S. environmental and labor laws and through its partnership with Trees for the Future, JadeYoga plants a tree for every mat sold.
