Thinksport introduced their yoga mat because a majority of the mats available today are made of harmful materials such as polyvinyl chloride (PVC) and polymer “environmental” resin (PER). So, Thinksport first and foremost set out to find a safe material that adhered to their strict chemical policy. However, Thinksport didn’t stop with just a safe material. they went on to develop a mat to be the highest performing and most comfortable mat possible.
