An incontinence booster is a pad-shaped insert that can be added to an adult diaper to increase absorbency. Easy-to-Change Design: Designed like an incontinence pad, booster pads are easy-to-change, making them perfect for on-the-go use; simply remove the soiled pad from your incontinence underwear or adult diaper, discard it, & replace it with a fresh booster pad for added protection.
