1/2” yoga mat. Great quality for the money.
Color: Aqua
I bought this yoga mat primarily for the 1/2” padding. I like the color and appearance with the ribbing on one side. I’m an older person and it’s difficult and painful to get down on my knees. This mat is comfortable and so easy to use. Doing my stretches and yoga are so much easier for me.

Great Mat, Slight Grip Issue (lika all mats)
Color: Black
Comfortable and solid for workouts, but it can be a bit slippery on the floor during intense poses. Still a great overall yoga mat.

The tear-iest anti-tear mat
Color: Green
The good: It's super thick and squishy. So it has that nice bouncy feeling when you're using it. The strap is easy to secure on the mat as well once it's rolled up. The color is also super cute. The bad: it's not Anti-Tear. It says in the name that it is, but the second I got it it tore. Only a little bit but still. For how cheap it is, I don't mind, but keep that in mind if you're buying this.

Love
Color: Deep Wine
This is a great quality, thick and pretty colored yoga mat! It's easy to roll up and put away and of course, just as easy to sanitize than the yoga mats with the little dips and crevices in their designs.

Great Knee Support
Color: Blue
The 1-inch thickness provides exceptional support and cushioning, making it ideal for a variety of exercises beyond just yoga. The high-density foam used in this mat is a game-changer. It not only cushions my joints but also retains its shape remarkably well. The carrying strap is a convenient addition, allowing for easy transport wherever I go. Plus, the mat is easy to clean, which is a huge plus after sweaty workout sessions. While the extra thickness might not suit everyone's preferences, especially if you prefer a thinner mat for certain poses, I find it perfect for my needs. It strikes an excellent balance between comfort and stability, providing the right amount of cushioning without compromising stability during balancing poses. Overall, the BalanceFrom All Purpose Yoga Mat will become an indispensable part of my fitness routine. Its durability, support, and easy maintenance make it a top choice for anyone seeking a reliable exercise mat for various workouts.
