Manduka's renowned eKO mat is new and improved. It offers an unparalleled grip to perform even in the sweatiest of conditions. In addition to its superior grip, the mat provides exceptional comfort and performance. The eKO mat is eco-friendly and made from biodegradable, non-Amazon harvested, and natural tree rubber that cushion and supports your body while protecting the planet. The new rippled water top surface features an innovative, sealed-cell natural rubber surface that creates a hygienic barrier and excellent loft and recovery. These natural rubber mats use a toxic-free softening process and are completely free of toxic foaming agents and plasticizers found in other mats. The eKO represents a bright future for the eco-friendly yoga mat - it leaves behind no footprint in landfills, but will definitely make a lasting impression in the studio.
