Kettle hat

A kettle hat, also known as a war hat, is a type of helmet made of iron or steel in the shape of a brimmed hat. There are many design variations. The only common element is a wide brim that afforded extra protection to the wearer. It gained its common English language name from its resemblance to a metal cooking pot (the original meaning of kettle). The kettle hat was common all over Medieval Europe. It was called Eisenhut in German and chapel de fer in French (both names mean "iron hat" in English).
