This unique belt includes 24 magnets sewn into breathable elastic, and provides abdominal and lower back support. The multi-panel knit elastic material reduces pressure on the lower back and produces a slimming appearance when worn underneath clothing. It is ideal for people who lift and move heavy objects, or who need abdominal support after an operation or childbirth. Simple hook-and-loop closure. Available in four sizes (small, medium, large, extra large).
