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. 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).
