I was hesitant to purchase this due to the price, but decided to take the plunge when a friend and yoga instructor recommended it. I only wish I'd bought it sooner! It's as grippy as they say it is. I used to hold tension in certain poses, focused on not slipping or falling. My first time using the mat and I was able to just BE. It felt incredible. I can't recommend this mat enough. It's a very firm foam, so I appreciate the extra cushioning of the 6mm thickness. The firmness adds to the stability without compromising comfort. It's totally worth the price!
