Great quality mats - they feel so durable. I bought these for classes I teach, and I've had students buy their own mats after trying these. The only downside is that when they first arrive, they have this coating on them which is super slippery. It takes a few washes (following the instructions) for this to wear off so you can do a downward facing dog without sliding all over the place! Once this is sorted though, they are really comfy mats offering great support.
