A flight suit is a full-body garment, worn while flying aircraft such as military airplanes, gliders and helicopters. These suits are generally made to keep the wearer warm, as well as being practical, and durable. Its appearance is usually similar to a jumpsuit. A military flight suit may also show rank insignia. It is sometimes used by Special Forces as a combat uniform in close quarters battle or visit, board, search, and seizure situations, for its practicality.

A jumpsuit is a one-piece garment with sleeves and legs and typically without integral coverings for feet, hands or head. The original jump suit is the functional one-piece garment used by parachutists.
