The ProFlex 1100SF Standard Spandex Back Support Brace is designed to remind workers of proper lifting techniques while also enhancing the body's intra-abdominal pressure, moving the stress away from the spine for back-pain relief. 280D spandex construction and non-conductive Sticky Fingers stays ensure durable, long-wear performance. Innovative, easy-adjust Power Panel Positioners keep all tension bands close to hand, so it's easy modify support-tension to the task at hand. Before lifting heavy objects, simply tighten the support belt to enhance the body's intra-abdominal pressure; and after lifting, just loosen the belt to achieve a wider range of motion. Adjustable, detachable suspenders along with flexible sizing and excellent waist/shoulder adjustability keep the brace in place. Machine washable—machine-wash cold and air dry.
