The Manduka eKO mat is the only choice for those who want a high-performance, durable yoga mat and are passionate about protecting our planet. The top surface is an innovative, proprietary closed-cell natural rubber. The sea-grass texture finish and superior cushioning are kind to your body and the environment. This natural rubber mat uses a toxic-free softening process and is completely free of foaming agents and plasticizers found in other mats. The eKO represents a bright future for eco-friendly yoga mats - it leaves behind no footprint in landfills, but will definitely make a lasting impression in the studio.
