Helm

Download Article

The helm, or helmet, protects the knight's head in combat. A mind is a terrible thing to lose, and so is an eye, an ear, or a nose. The helm protects them all! The thin slit close to the top allows the knight to see out, and the holes by the nose and mouth let in a small amount of fresh air. Knights would also wear an arming cap and a mail coif underneath their helmet for extra padding and protection. The cap was a hood made of many layers of fabric, whereas the coif was made of steel chain mail links.^{[1]

- Did you know? The medieval era saw many different helmet designs. Some, like the Great Helm, covered the entire head and had a thin eye slit for vision. Others were more like caps and only covered the top of the head, and sometimes the bridge of the nose or the ears.

Gorget

Download Article

The gorget (gor-juht) is a collar that protects the knight's throat. Without this essential piece of wraparound armor, there would be a gap between the helm and the breastplate. A knight would then be vulnerable to attacks on his neck, where an enemy's sword could easily slice through his carotid artery or even cut off his head.
- Did you know? The bevor is a piece of plate armor similar to the gorget. But instead of just protecting the throat, the bevor also curves upward to protect the chin and the lower half of the face.^{[2]

Haubergeon

Download Article

The haubergeon (hab-er-juhn) is a short coat of mail worn under plate armor. A knight might say that back in his day, he wore a haubergeon made of chain mail instead of plate armor. Later in the medieval period, however, knights wore this sturdy coat underneath their cuirasses. The combination was the ultimate protection on the battlefield.^{[3]

- Did you know? Knights might also wear a gambeson instead of or in addition to a haubergeon. A gambeson is a quilted fabric jacket or tunic that gives the knight even more padding to resist blows.^{[4]

Cuirass

Download Article

The cuirass (kwer-ass) shields the knight's chest and back. Another place you definitely don't want to be stabbed is in the heart, or it's curtains for you! Getting stabbed in the kidneys or getting your intestines carved out isn't fun, either. To prevent these grim scenarios from occurring, knights would wear a large piece of armor called the cuirass. The front part is called a breastplate, and it covers the knight's entire torso. It also comes with a backplate to help protect against attacks from the rear.
- Did you know? If you were a medieval knight who was wounded or fell during battle, all was not lost! You might not have been slain. Instead, you might have been ransomed, meaning held captive until your lord or king paid a certain sum of money for your release.^{[5]

  - If you were a lowly infantryman, however, you probably wouldn't have such good fortune.

Plackart

Download Article

Let's say you're a knight who's really worried about your guts spilling out from a well-placed stab. In that case, in addition to your cuirass, you'll want to wear a plackart. This piece of armor reinforces the breastplate, offering an extra layer of metal between you and the pointy end of your enemy's weapon.

6

Fauld & Culet

Download Article

A slice to the waist or hips is terribly inconvenient, but even more so is a cut across the buttocks. The fauld and culet fortify these sensitive areas. The fauld wraps around the front of the torso under the breastplate, whereas the culet wraps around the lower back. Both are apron-like pieces of armor with overlapping layers of metal.

7

Tassets

Download Article

Tassets hang from the fauld and protect the knight's upper thighs. If you want to hobble through the battlefield in excruciating pain, getting stabbed in the thigh is the way to do it. But if you're a sane knight who wants to avoid this terrible experience, wear tassets. These simple plates of armor hang from the bottom of the fauld or the breastplate and act as your upper thighs' personal shields.

Pauldron

In some cases, this meaty piece of armor also protects part of the chest—talk about being an overachiever!^{[6]

Research source} But when you're a knight, it's better to be safe than sorry, and pauldrons were essential pieces of a knightly ensemble. Some of them are equipped with extra pieces on the top called haute (howt-eh). A haute prevents swords, lances, and other weapons from slipping up the pauldron and wounding the neck or the head.^{[7]

Gussets

Download Article

Knights wore gussets! These triangular pieces of fabric or another material are still sewn onto clothes today to reinforce the garment's strength or provide more flexibility. Some knights wore chain mail gussets around their elbows and shoulders to make movement easier, while still protecting these sensitive areas.^{[8]

Rerebrace

Download Article

The rerebrace (reer-brace) protects the knight's upper arm above the elbow. This piece of armor provides shielding for the part of the arm between the shoulder and the elbow. In other words, it helps prevent weapons from piercing your bicep and rendering your arm useless.

Couter

Download Article

Getting whacked or sliced in your funny bone is no laughing matter. That's why a knight would cover it up by wearing a couter. This piece of armor wraps around the point of the elbow.^{[9]

Research source} The earliest versions of it didn't move, but later iterations were hinged to make it easier for the knight to bend their arm.

12

Vambrace

Download Article

The vambrace protects the forearm from the elbow to the wrist. It can be made out of steel plate armor, but also out of tough animal leather and hide. Knights used it to deflect blows aimed at their head or neck by their enemies. It came in especially handy in close combat, when long sword blades are of little use in defense.
- Did you know? Some people confuse the vambrace with a leather sleeve called a bracer. But while vambraces are often made of steel and are used by knights bearing swords and lances, bracers are less sturdy and are worn by archers. Their primary purpose is to protect the inside of the archer's arm from the bowstring when it bounces back.

13

Gauntlet

Download Article

Think of this piece of armor like a big glove. Except it does more than keep you warm in the winter: it also protects you from pulling a Luke Skywalker and getting your hand chopped off! The fingers have articulated joints, so the knight can still hold weapons, their horse's reins, and whatever other objects they may need.

14

Cuisse

Download Article

In Mel Brooks' classic slapstick comedy Young Frankenstein, Gene Wilder's character accidentally stabs himself in the thigh with a scalpel. But if he had been wearing a cuisse, the scalpel blade would have glanced right off! Of course, a knight is vulnerable to attacks from all sorts of terrible weapons, so wearing thigh protection is an absolute must.^{[10]

Poleyn

Download Article

A poleyn (po-lane) is a piece of armor that wraps around the knee cap. Also called a knee cop, the poleyn protects a knight's knee from getting slashed and impairing their ability to walk upright. It also makes a lot of extra noise when their knees are knocking in fear of the enemy!^{[11]

- Did you know? A fan is an optional piece of armor some knights wear to protect the backs of their knees. The piece attaches to the poleyn and sits on the side of the kneecap. It flares out so that any weapons that come into contact with it simply slide off.
  - This TikTok by @robinswords shows the fan in action!

16

Greave

Download Article

To prevent their shins and ankles from getting banged up or sliced, knights would wear concave pieces of armor that extended from their ankle all the way up to the poleyn around their kneecap. Some greaves only shield the front of the left, whereas others wrap all the way around the calf on the opposite side of the leg.

17

Sabaton

Download Article

The sabaton (sab-uh-ton) protects the knight's foot and toes. There'll be no toe stubbing in these shoes! A sabaton is basically an armored shoe that fits over the toes and foot and connects to the greave. The toe of the sabaton can be round or pointed, depending on the fashion of the era.^{[12]

Research source} If it's pointed, your close combat kicks will pack more of a punch!
- Did you know? You may think that wearing all this armor would wear a knight down, but scholars say it wasn't as heavy as we think! Knights had to be able to move around on the battlefield, as well as mount and dismount their horses, and their armor was light enough to allow these actions.^{[13]
