For over 500 years, Switzerland has provided young soldiers to protect the Pope in Vatican City. They are among the most photographed people in the world, resplendent in their metal armor cuirasses and billowing yellow and blue striped uniforms.
The Swiss Guards have topped their "Gala uniforms" since the early 1900's with heavy metal helmets stamped with the coat of arms of Pope Julius II, who formed the corps in 1506. No longer.
The Swiss Guards are getting new plastic helmets that are 3D printed. The lighter, cooler, UV resistant helmets are fashioned in the same 16th Century style as the old ones, but are black rather than the silver metal color that matched the cuirasses.
The new helmets are purely ceremonial and not recommended for actual combat. A suitable warning will doubtless be put in a conspicuous place inside the helmet.
