The CorFit’s upward and inward pressure supports stretched or weakened abdominal muscles and reduces stress on the lower back. The support is so comfortable and supportive, you’ll even look forward to wearing it. The plush elastic back panel is made with flexible posterior stays; adjustable double side pulls provide customized abdominal compression. Wicking material draws moisture away, helping you stay cooler. The soft, CorEdge? Finish around top and bottom edges adds comfort without binding or irritation.
