ProFlex 1625 Standard Elastic 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. Flexible and breathable, the premium, all-elastic, 7-1/2" body delivers extra-firm support to help lessen lumbar strain and address chronic back pain. Contoured, high-cut front panel allows easy mobility and a comfortable fit for all-day wear. Stays are made of nonconductive polypropylene for long-lasting integrity. Adjustable, outer elastic panels pull snug before lifting to provide the exact fit and desired level of tension. Adjustable, removable, shoulder straps keep the belt on standby until the next lift. Machine-washable brace fits waists from 38" to 42".
