This biobelt pouch was flown aboard Apollo 11 in July 1969. It was assigned to command module pilot Michael Collins for use during the mission.
Biobelts were constructed of a cotton duck base with Teflon-coated Beta-cloth pockets into which were fitted an electrocardiograph signal conditioner, an impedance pneumograph signal condtioner and a DC-DC converter. They were fitted with snap fasteners which attached to either the constant wear or liquid cooling garment, as activities indicated.
Transferred to the National Air and Space Museum from NASA in 1970.
