The close helm was a helmet that enclosed the entire head of the knight, ending at the bottom in a gorget, which was usually composed of several lames used to protect the neck. It was very similar to an armet, but opened in a different fashion. While an armet had two hinged cheek pieces, the close helm’s bevor would hinged upward like a second visor.
The front section of the gorget came up with the bevor, allowing the knight to put the helmet on with the bevor up, then close the bevor. Often, the close helm also had a rondel at the back, to protect any vulnerable strapping.
The close helm was used in tournaments, jousts, and warfare. Depending on the application, it could range anywhere from eight to twelve pounds, and had varying degrees of face protection.
