For the aficionado of ESG (Environmental Social Governance), here is the eco-friendly TPE (ThermoPlastic Elastomers)mat by agoy. No PVC. No Latex. No heavy metals. Odorless. Recyclable The agoy Earth Mat naturally provides excellent traction and therefore stability in your yoga movements. It has amazing grip which is enhanced by its exclusive surface pattern. The structure of the mat gives great support and because it isn't spongy like so many yoga mats, it doesn't bottom out, lessening impact with hard floors. In fact the performance of agoy's Earth Mats is in this respect equivalent to regular PVC mats of double the thickness. This also makes it lightweight in comparison to many yoga mats. Our Earth Mat is also hygienic - it doesn't absorb sweat and the natural characteristics of the material prevents bacteria and fungal growth So what does it mean to be decomposable? The agoy Earth Mat breaks down under high temperature and/or high pressure over a period of 5-10 years. For example, in waste sites, when TPE breaks down, it releases only CO2 (carbon dioxide) and H2O (water). And if burnt, becomes 100% CO2 and H2O. So...truly recyclable back into Mother Earth. Finally, the packaging (wrapper) is made of biodegradable starch ! Re-use it; or cycle it easily back into the environment. Chocolate Earth mats come in 2 thicknesses: Deluxe at 1/5"; Classic at 1/4". The Classic Mat is extremely lightweight and carried by yogis and yoginis who travel on business.
