The blanket sleeper or footie pajama is a type of especially warm sleeping garment worn primarily during the winter in the United States and Canada. The garment is worn especially by infants and young children. Typically, but not always, the blanket sleeper consists of a loose-fitting, one-piece garment of blanket-like material, enclosing the entire body except for the head and hands. It represents an intermediate step between regular pajamas, and bag-like coverings for infants such as buntings or infant sleeping bags (Terminology and Variations sections below).
