The Apollo Bio-Harness Assembly was worn under either the intra-vehicular (IV) or extra-vehicular (EV) pressure suit. This assembly was flown on Apollo 11 in July 1969. However, it was not worn during the mission.

The complete assembly consisted of a cotton duck belt, which was fitted with snap fastners and teflon-coated beta cloth pockets, which attached the assembly to either the constant wear garment or the liquid cooling garment.

The components consisted of an electrocardiograph signal conditioner, an impedance pneumograph signal conditioner and a DC-DC converter. These instruments monitored the physiological functions of the astronaut.
