The ProFlex 100 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. Featuring 280D spandex body material, this back support brace provides moderate level of support and also features mesh material on the backside for increased airflow. Rubber track webbing stays are sewn onto the interior to help keep support in position and prevent it from riding up. SIZ
