Helmet

The steel head-covering worn during armored combat. The helm must be of at least 16 gauge thickness, but most serious combatants prefer the thicker 14 or 12 gauge for their greater dent-resistance. See also specific types of helmets: barbute, barrel helm, bascinet, Phrygian helm, pot helm, sallet, spangenhelm and sugarloaf helm.

See also helm. Jocularly called a hat, lid or top.
