This communications carrier was used by an unknown astronaut during training sessions prior to the Apollo missions of the late 1960s and early 1970s. Communications carriers were worn during launch and the mission, and were affectionately known as the "Snoopy Cap" from its resemblance to a famous cartoon character of the era.
It was constructed of an elastic center portion with Teflon fabric sides containing the communications equipment and mouthpiece. It fastened beneath the chin and was worn through the launch sequence and while in the lunar module and on the lunar surface.
NASA transferred this communications carrier to the Smithsonian in 1977.
