plastic pants

Plastic pants (also known as waterproof pants, plastic panties, diaper covers, nappy covers, nappy wraps, wraps or pilchers) are devices worn over a diaper with the purpose of containing liquid or solid waste that could leak through the fabric. Today, plastic pants are usually made out of polyvinyl chloride (PVC) or polyurethane (PU), though, in some instances, latex rubber is still used. Latex rubber has significant drawbacks in these applications: it is easily damaged by rough handling, oils, creams, and ointments; it does not allow air to ventilate; it also makes a characteristic rustling noise when moved, which limits its use in situations where discretion is necessary.
The availability of inexpensive, and easily worked, man-made waterproof materials since the 1950s has significantly improved the quality of life of those with continence problems, and has contributed to changes in clothing style and freedom, especially for infants and menstruating women.
