I was using this as a yoga rug on top of a yoga mat. Material: ・Surface: Suede-like material ・Back: Natural rubber Size: ・Please check the actual size in the images. ・Thickness: 1.5 mm After use, I was washing it with water in the shower. I have several similar mats, so I used them in rotation. ※ Can be used alone or in combination with a mat ◎ It's great for preventing slips on the mat, which I think is also good for preventing injuries ◎ (I initially used a yoga rug with non-slip backing, but it still slipped during hard movements, and after searching around, I found this mat.) It's also foldable, so you can fold it up compactly for storage. ⚪️ I will also include a new, unused mat pouch, although it's not specifically for this mat. Please comment if you have any questions.
