Grip & Durability (Top Layer): ???Sea Grass??? surface texture is naturally grippy; the closed-cell surface keeps out moisture (sweat) from seeping into the mat and breeding bacteria for better durability.

Dual Function Cushion (Bottom Layer): Thicker, open-cell bottom layer provides lightweight cushion. It can also be reversed to function as the top surface for more traction. Just flip over for a sweatier practice!

Stretch-resistant Scrim (Center): Made from biodegradable cotton and polyester blend; Binds top/bottom layer together with heating process, eliminating need for toxic glues.

Natural & Biodegradable: Made from biodegradable, non-Amazon harvested tree rubber with non-toxic foaming agents and non-AZO dyes.
