PLUSH! Fabulous yoga mat!
Color: Black, Style: 1/2 Inch
SO comfortable! It feels like a soft memory foam padding. I use it for several exercise classes and it is great for all of my needs! I love the strap it comes with to keep it rolled up in between classes and the ability to carry it anywhere.

very comfortable and thicker than a regular yoga mat
Color: Pink, Style: 1/2 Inch
This yoga mat is very comfortable and thicker than a regular yoga mat. The quality is excellent, and it doesn't have that strong rubber smell that many mats have. I'm very happy with it!

Great product
Color: Black, Style: 1/2 Inch
Nice yoga mat. Perfect thickness for me. Love that I can roll it up and put it out of the way. Gives great knee support and the material is comfortable.

Good quality and light weight w/ stand
Hand Orientation: Right, Color: Blue/Black
Our grandson is beginner and we bought this set for him and he loves them. He’s 13 so he can’t drive the cart and these are light and easy to carry if he is without a cart.
