This 3-in-1 maternity belt, post partum belt and pelvis belt is adjustable all over its length to ensure a perfect fit. It can be used as: 1. MATERNITY BELT: With the adjustable second layer, the belt wraps around your belly and waist, lessening the burden of pregnancy weight. 2. POSTPARTUM BELT: The postpartum belly wrap is highly recommended by doctors after pregnancy as a postpartum abdominal support and helps you get back to your pre-pregnancy waist size! 3. PELVIS BELT:Your belly and back are in need of proper support far beyond the pregnancy period, in order for your muscles and spinal column to smoothly transition to their pre-pregnancy positions. This pelvis belt provides support for your pelvis.
