This leg cover belongs to the Advanced Crew Escape System (ACES) exterior layer. When put together with the upper cover, the suit is a one-piece pressure garment assembly with integrated pressure bladders and ventilation system. Oxygen is fed through a connector at the wearer's left thigh and is transmitted to the helmet, via a special connector at the base of the neckring.

The ACES suit was designed to be worn during launch and re-entry on the Space Shuttle. The David Clark Company produced the suit in an international orange color, instead of the white or silver color used in previous models. The orange color allows rescue units to easily spot the astronauts in case they are forced to bail out over the ocean. The ACES was first used in 1994.

NASA transferred this to the Museum after the end of the Space Shuttle program.
