Some people also call plastic pants 'rubber pants' even though they actually mean plastic pants.The terminology 'rubber pants' is incorrect.Plastic pants (also known as vinyl pants,vinyl being a type of plastic) are generally considered to be the best type of pants to cover cloth diapers with - they're usually the most durable, they tend to be the least expensive type of waterproof pants, and they have excellent wicking capabilities (meaning how well liquid is dispersed). As a result, you need to cover the diapers with a pair of waterproof pants. Unlike disposable diapers, cloth diapers do not have a waterproof outer layer. Buy plastic pants to wear over the cloth diapers.
