Fitting: Align the abdominal support to the mid-back. Careful not to place the support too low on the back; it should rest slightly above the buttocks. Pull the side panels across the front of your body and secure into place. Thie support may require some readjustment throughout the day; this can be done by unfastening and pulling the support tighter. Sizing: Circumference of man's waist or woman's hip: L/XL: 45-62 inches. Care: Hand wash in cool water with mild soap. Wrap in towel to remove excess water. Air dry away from heat.
