This is an Apollo pressure helmet used by various astronauts during training sessions.
The Apollo pressure helmet was a blow-molded, clear polycarbonate shell with a molded bayonet base which was bonded to the helmet neck ring. The neck ring was the male half of the suit neck-ring assembly, and there were two configurations used on Apollo suits which were not interchangable. The earlier configuration was anodized blue, with the later configuration being anodized red.
