a type of protective underwear (diapers) that kids and teens who wet the bed use to stay dry; goodnites have a cloth like layer and look and feel like real underwear; has an absorbant inner pad to soak up wetness; the only thing bad about them is that they sometimes leak, but leak gaurds on new versions do help
