This life vest was part of the emergency equipment carried aboard Apollo 11 in July 1969, and was assigned to command module pilot Michael Collins for his use.
Life vests were part of the emergency survival equipment issued to astronauts during the Apollo program. The unit was worn around the upper torso, with straps over the shoulder, and fastened with a buckle in the front. Upon leaving the spacecraft, the two vests would have been deployed.
NASA transferred this vest to NASM 1979.
