This is a one piece winter flight suit used by the Japanese Army Air Force during World War II. This suit was lined with rabbit fur from the waist to the neck. There is no sewn in name tag in Army flight suits, only a stamp that indicated the supply depot that issued the flight suit. There were, however, spaces on the inside of the suit so the pilot could write his name if he desired.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
