All of our Helmets are made from 18 guage steel. This is the best steel for helmets. They all come with good quality leather inserts so that the helmets are comfortable to wear and adjustable to the size of the persons head. All hair is genuine hoprsehair which is traditional and also looks far superior to synthetic imitations. We have everything from Spartan, Roman, and Gladiator Helmets, which are all from over 2000 years ago, up to more modern Knights Helmets.
