Designed for everyday working or driving, the Mustang Back Belt enhances positive intra-abdominal pressure to equalize harmful stress away from the spine. With an 8 1/4-inch-wide back panel, polypropylene mesh body, four super-memory plastic stays and solid elastic side bands, the belt helps prevent back pain and injury. Two silicone grip strips inhibit roll up, and the stiffening mesh at the abdominal closure reduces front rolling.
