Developed by an orthopedic surgeon, this is the back brace that maintains correct curvature of the lower back without applying uncomfortable pressure on the abdomen. The u-shaped brace's soft silicone cups rest comfortably on the hips, not the stomach, providing more comfort when breathing or eating and better freedom of movement while walking or during light exercise. The steel brace exerts a gentle pressure on the intervertebral discs to encourage proper posture and strengthen core muscles that support the natural curvature of the spine, helping relieve lower back pain. The brace fits over or under clothing and adjusts to accommodate 28" to 52" waists. 11 1/2"-14' W x 7" D x 3 1/2" H. (2 lbs.)
