Our range of eco yoga mats includes a choice of two different materials as an alternative to traditional PVC mats. The most eco friendly yoga mats we offer are made from either dry natural rubber/latex or from TPE as being from predominantly natural resources these mats are more sustainable and will biodegrade over time. As well as being more environmentally sounds natural rubber and latex mats offer the best grip of any mats available. TPE is a type of lightweight closed cell, synthetic rubber which our Evolution yoga mat is made from offering excellent grip in a lightweight mat.
