This towel actually made my mat more slippery. And to make matters worse, the manufacturer won't accept returns. 1 star

I bought the smaller hand size towel because I didn't want to wash the big towel all the time.
They warn that it will bleed if you don't wash it twice before the first use, but I didn't find that to be true.
You have to wet the towel before you use it. I still find that my hands slide, especially when holding down dog for a long time, but it's better than not using the towel. It's also better than using a hand towel. So, dont' think that it's going to be magic, but it will improve slippage. 4 stars

This item has been a wonderful purchase for me! During hot yoga sessions, my hands always get slippery, but this towel prevents me from slipping. During down dog, I am now sturdy and not slipping all over the place! I would recommend to spray it with water at the beggining of a class because when it's dry, it doesn't work as well. 5 stars

the towel doesn't slip on the mat but my hands still slip on on the towel. I was looking for something that would help my hands to not slip on my yoga mat. 4 stars

Worked exactly as advertised for me. I No longer slip when doing down dog. Small and portable and easy to wash. 5 stars
