Underoos is a brand of
underwear primarily for children, produced by the
Fruit of the Loom company. The packages include a matching top and bottom for either boys or girls, featuring a character from popular entertainment media, especially superhero comics, animated programs, and fantasy/science fiction. In many cases, the garment mimics the distinctive costume of the character, encouraging the wearer to pretend to be the character. In others it features an image of the character or logo on the undershirt.
