The CorFit System LS Back Support provides compression to help stabilize the spine and ease lower back pain by creating intra-abdominal pressure. It also helps improve posture and serves as a reminder to use proper lifting techniques by limiting the motion of muscles and ligaments. Our patented, proportional sizing system provides a proper fit in height and length to accommodate various body sizes. Flexible internal stays provide support and stability as well as help prevent the sides from rolling. Easy closure assists provide additional leverage with minimal effort for extra compression and a secure fit which is ideal for users with arthritis or weakened muscles. The soft elastic CorEdge finish on top and bottom edges offers added comfort and flexibility. Soft material wicks away moisture, keeping the body cool and comfortable. The anatomical form contours to the natural curves of the waist and hips for comfort. Dual elastic side pulls provide firm compression. The CorFit system properly fits everyone while providing comfort, compression, flexibility, and stability. This product contains no latex.
