Disposable incontinence pads and liners offer light to moderate protection to address a wide range of bladder control issues.  Bladder control pads with a moisture-proof barrier that can be worn inside of regular underwear come in various sizes, shapes and absorbency levels from pantyliners to ultimate coverage pads. Booster pads, also called diaper doublers or diaper liners, which have no moisture-proof barrier and therefore allow the pad to saturate through to the next layer of protection, are designed to be worn inside of an incontinence undergarment to increase overall absorbency.
