Jumpsuit

Jumpsuit is a piece of clothing, originally referred to the functional one-piece garments used by parachuters/skydivers. More recently, it has come to be used as a common term for any one-piece garment with sleeves and legs.

The original skydivers' jumpsuits were simple garments designed to insulate the body from the cold of high altitudes and minimize risk of covering important handles and grips. Today, however, the garment has found other uses.
