This biobelt pouch was flown aboard Apollo 11 in July 1969. It is not identified as to which astronaut it was assigned.
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.
