Maximum joint comfort and durability
Color: Pink, Style: 1/2 Inch
I absolutely loved the color, and it offers incredible cushioning without sacrificing stability during balance poses. It is dense, doesn't lose its shape, and springs back instantly. The materials are high-quality, and it doesn't have that strong plastic smell that others often have. It is worth every penny for the comfort it provides.

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.

Love my mat!
Color: Pink, Style: 1/2 Inch
I’m new to stretching and recovery classes, and there is a lot of floor work. I was using the gym mats, but my knees, lower back, and glutes were hurting from being on the floor. This mat is the perfect thickness and feels wonderful during floor exercises. It gives me the extra cushion I need without being difficult to use. It’s also lightweight, durable, easy to clean, and easy to roll up for transport. The pink makes me smile. That said , the mat makes the classes more enjoyable.
