The Launch Entry Suit (LES), known as the “pumpkin suit,” is a partial-pressure suit that was worn by all Space Shuttle crews for the ascent and entry portions of flight from STS-26 (1988) to STS-65 (1994). It was completely phased out by STS-88 (late 1998) and replaced by the ACES suit. The suit was manufactured by the David Clark Company of Worcester, Massachusetts.

The LES was first worn by U.S. Air Force pilots, replacing a similar suit worn by SR-71 and U-2 pilots, and was identical to the suits worn by X-15 pilots and Gemini astronauts. Each suit was sized individually, although most suits could be worn by astronauts of different heights. It included a parachute and flotation device.
