Manduka's Black Mat PRO (formerly the Black Mat) upholds a somewhat legendary status among yogi's worldwide as the highest-performing yoga mat. After 10 years in production, the Black Mat PRO is still going strong. Made of closed-cell PVC, this mat boasts a super rigid, closed cell structure that won't absorb sweat and stays clean easily. Dot-pattern on the bottom helps keep the mat glued to almost any sturdy surface. Textured fabric-like finish is super sticky and keeps slippery hands and feet locked into the ground.
