MY premium yoga mats are 24" wide x 72" tall x 0.25" thick and made from natural rubber with a blended microfiber top surface. The top of the mat has the image printed on it, and the back is solid black with textured dimples for better floor grip. These are very nice and high quality not the cheep foamy stuff! If you do Yoga you will love this mat! You are guaranteed to love it, or just return it within 30 days.
