A knight had many pounds of armor that he had to wear to protect himself from arrows and swords. The armor was put on by one or more squires or pages. First, the knight put on a linen shirt and drawers, which were similar to loose boxer shorts. Over the drawers he wore a long woolen hose and arming doublet, which was a shirt with chain mail padding on the arms and chest. Around his neck, he wore a chain mail neck collar. Breast and back plates were strapped onto his chest, which had a little skirt of armor attached to protect his groin. More armor was strapped onto his arms, legs, hands, and feet. This armor came in many pieces so that the knight would be able to move more easily. The last piece of armor placed on the knight was his helmet. The helmet was very hot, so if the knight was not going into battle immediately, he would hold the helmet by his side. The knight also used a metal or wood shield to ward off enemies blows during a battle. This shield was carried on one arm, usually the left, and the sword was carried with the other.
