prAna Synergy Towel Yoga Mat

I love this product. I have tried many other products designed to prevent slipping caused by excess sweating in a yoga class. I practice warm yoga and I tend to sweat heavily, even if the class isn't heated. This is the only product I've found that actually works as advertised.My hands and feet never slip around on this product, whether I'm at the beginning of a yoga workout or I'm finishing a hot, vigorous workout and I've saturated the entire towel. I do not slip.The towel itself also sticks very well to the mat or floor underneath it. So, not only do I stick to the towel, but the towel also sticks to the floor with its heavy rubber lining for the under side of the towel. All together this creates a totally stable, slip-free surface for me during my workout. The rubber lining on the bottom side of the towel also appears to keep my yoga mat underneath the towel totally dry, even after I've had an extremely vigorous workout and I've saturated the towel. This helps keep my mat protected from the microbes, toxins, and general filth that come along with sweat, thus keeping my mat cleaner, longer. I don't have to deep clean my yoga mat as frequently. I love this feature because I have a thick 8 mm Jade yoga mat which takes forever to dry when it is given a deep cleaning.There are a few drawbacks to this product. First, it's the most expensive mat towel I've found. It works the best, but it'll cost you more money.
