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.

worth it for the price
Color: Pink, Style: 1/2 Inch, Color: Pink, Style: 1/2 Inch
i got the pink and it’s a super cute color in person! came with the strap which was nice too. thick and comfy - not sure how durable it is, as i just recently purchased it. only thing was the smell after taking it out of the box. very chemically scent but only lasted about a day. overall i love it and hope it holds up!

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.

For the price it’s a really good yoga Matt
Color: Blue, Style: 1/2 Inch
For the price it’s not bad. I use for multiple things, not just yoga, it’s nice and thick I used it to lay on the floor and fix my table and gaming chair and to get under hard to reach places when I don’t want lay directly on the floor. it’s soft enough not to hurt my back very well put together strong material.

This is a nice mat for floor exercises.
Color: Aqua, Style: 1-Inch
I had some lower back issues and went to physical therapy. I used this mat for my floor stretches and exercises at home along with my big rubber ball. It made the floor work so much more comfortable. Beware of the smell. When I unroll it I still smell that “memory foam” odor, which takes some getting used to. I aired it out as instructed, twice, and it persists. It’s a wonderful mat so the odor is not a deal breaker. I’d buy it again.
