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. For long wear, patented, nonconductive, Sticky Fingers stays deliver firm, continuous support with greater gripping properties to prevent the back support from riding up or moving. Innovative, Power Panel Positioners tighten for enhanced support while lifting and keep panels in place when not active. The 280D spandex body is stretchable for comfort and offers extra-firm support. Adjustable, detachable suspenders keep brace in place. Machine-washable brace fits waists from 25" to 30".
