The convenient and versatile Harbinger Fitness Ribbed Durafoam Mat is a great way to keep up with your exercises while youâ re on the go. Non-skid ridges prevent the mat from slipping. An integrated strap makes it easy to carry, so you have no problems doing your yoga, pilates, stretching or floor exercises wherever it is most convenient. Founded in 1988 by fitness enthusiast and entrepreneur David McCrane, Harbinger swiftly became the brand of choice for weight lifters and strength trainers worldwide. It began with an innovative Wrist-Stabilizing Glove. Originally intended to mitigate wrist injuries for skateboarders, McCrane quickly realized the benefit of his product for weight lifters. Teaming up with 8-time Mr. Olympia body builder Lee Haney, they pioneered Harbinger as the source for high quality, carefully engineered gloves, belts and strength training accessories. Since then, Harbinger has expanded into weight lifting accessories, including wraps, straps and speed ropes. With proprietary technology and advanced design, Harbinger drives the category and continues to deliver new, innovative products. 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.
