Kettle hat

Steel helmet in the shape of a brimmed hat

A kettle hat, also known as a war hat, was a type of combat helmet made of iron or steel in the shape of a brimmed hat. There were many design variations, with the common element being 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 kettle hat was common all over Medieval Europe, and was called Eisenhut in German and chapel de fer in French.
