Zennery Non-slip Yoga Mat is used by yoga and exercise enthusiasts. The extra-thick 6mm memory foam does not feel overly dense or bulky. It provides comfort and support so your knees and elbows stay healthy and injury free. The two sided surface of the mat is non-slip to grip the floor; the other side has extra cushion to protect your joints. In addition, included is a durable and adjustable harness strap for your convenience and ease to take your mat from home to the gym, workout studio or wherever go to strike a pose.Namaste.
