Rubber pants are baggy, balloon styled panties that are pulled on over top of a baby's diapers, usually cloth diapers, to help prevent leaking, and to prevent the soiling and wetting of outer clothing worn by the baby, and to keep surrounding furnishings dry and clean.

Rubber pants are manufactured out of 100% vinyl/plastic, have gathered elasticized waistband and leg hole openings, and pull-on like panties. Rubber pants are most commonly used in households with babies wearing cloth diapers.

Rubber pants are also used for the purpose of toilet training a baby from the stage of diapers, to the stage of underpants.
"Gerber" and "Babykins" are two specific names that manufacture rubber pants for babies today.
