The chanfron was designed to protect the horse's face. Sometimes this included hinged cheek plates. A decorative feature common to many chanfrons is a rondel with a small spike. The chanfron was known as early as ancient Greece, but vanished from use in Europe until the twelfth century when metal plates replaced boiled leather as protection for war horses. The basic design of the chanfron remained stable until it became obsolete in the seventeenth century, although late examples are often notable for engraved decoration. A chanfron extended from the horse's ears to its muzzle. Flanges often covered the eyes. In an open chanfron, the eyes received no protection. Hinged extensions to cover the jowls were commonly used for jousting tournaments. The enigmatic Torrs pony-cap from Scotland appears to be a bronze chanfron from about the 2nd century BC, perhaps later fitted with the bronze horns found with it.
Criniere
The criniere was a set of segmented plates that protected the horse's neck. In full barding this consisted of two combinations of articulated lames that pivoted on loose rivets. One set of lames covered the mane and the other covered the neck. These connected to the peytral and the chanfron. Light barding used only the upper lames. Three straps held the crinet in place around the neck. It is thought that thin metal was used for these plates, perhaps 0.8 mm. Mail armour was often affixed to the crinet and wrapped about the horse's neck for additional protection.
Croupiere
The croupiere protected the horse's hind quarters. It could be made from any combination of leather, mail, or plate armour.
Flanchard
The flanchards, used to protect the flank, attached to the side of the saddle, then around the front or rear of the horse and back to the saddle again. These appear to have been metal plates riveted to leather or in some cases cuir bouilli armour. They sometimes had openings designed to allow the rider to use spurs.
Peytral
The peytral was designed to protect the chest of the horse, while the croupiere protected the rear. It sometimes stretched as far back as the saddle.
Caparisons
Barding was often used in conjunction with cloth covers known as caparisons. These coverings sometimes covered the entire horse from nose to tail and extended to the ground. It is unclear from period illustrations how much metal defensive covering was used in conjunction. Textile covers may also be called barding.
Other features
Another commonly included feature of barding was protection for the reins, so they could not be cut. This could be metal plates riveted to them as seen in the images here, or chainmail linked around them.
