Like all Jade mats, the bottom layer is made sustainably with natural rubber - a rapidly renewable resource. The top layer is made with a unique textured polyurethane (PU) to deliver an extra dose of everything you love about yoga mats:
Extra Durable - PU surface for longer life
Extra Absorbent - PU surface absorbs sweat and is moisture wicking
Extra Safe - Antimicrobial (silver nitrate) surface
