This helmet is the transparent pressure bubble made for Neil Armstrong as part of the back-up suit designed and constructed in case of failure of his Apollo 11 flight suit.

The Apollo pressure helmet was a transparent bubble designed to attach to the spacesuit neck ring. It was constructed of a polycarbonate shell with a red anodized aluminum neck ring, a feed port, a vent pad and duct assembly attached to the rear and a valsalva device attached to the inner ring.

There were two configurations that were not interchangable used on Apollo suits; the earlier configuration was anodized blue, the later configuration anodized red.

Transferred to the National Air and Space Museum from NASA in 1972
