This helmet was used by a variety of astronauts during training sessions prior to the Gemini missions of the 1960s.
The helmet had a triple lens shield (visors) for visual, thermal, and micrometeorite protection. The two over-visors were constructed of Lexan and provided micrometeoroid and thermal protection for the faceplate. One visor was gold tinted to provide glare protection for the astronaut.
The helmet was constructed of fiberglass and epoxy resin and was molded to fit directly into the neck bearing disconnect. A Plexiglas visor, capable of being raised for access, was attached with pivots, and when lowered into pressure sealing position, it locked in place with a latch. Communication devices with suede-covered ear pads were incorporated into the helmet.
Transferred to the National Air and Space Museum from NASA in 1971
