Apollo 13 Lunar Surface EVA Helmet

The Apollo 13 extravehicular helmet, placed over the pressure suit, was the
first one to have a red stripe running down the top of it. This stripe would
help identify the commander in photos taken on the lunar surface. The gold
reflective material acts like sunglasses. Like the gloves, a
metal ring provides a connection to this "fishbowl helmet" that gives a wide
field of view and eliminates the visor seal that had been used in the Mercury
and Gemini program helmets. Can you see the fireproof cover layer that
provides additional protection?
