The Harbinger anti-microbial mat is great for stretching, Yoga, floor exercises, and Pilates. It's made from exclusive 5/8-in thick closed cell Anti-Microbial Durafoam, which prevents bacterial growth and odor and does not wear off over time and use. The non-skid ridges grip the floor to prevent slipping, and the removable strap makes it easy to store and carry.
