Our yoga extra cushion mats are designed to provide you with a safe and stable foundation upon which to build your yoga practice. Your yoga mat will allow you to grip the floor with your hands and feet, giving you more leverage and stability, thus preventing slipping and sliding in postures. It also cushions your knees, ankles, and other body parts, making your yoga practice more comfortable. We highly recommend this nonslip mat. It has excellent traction and is very durable and is washable. This is the original sticky mat!!! Combine it with our Cleaning Disinfectant. This product is Phthalate free.
