Running the times the loriga was replaced by the cuirass . Made of silvery steel and very heavy, it protected the entire volume of the knight's body, as if it were an articulated frame. It was a better protection element than the cuirass. It was reinforced at shoulders, knees and elbows. At the end of the Middle Ages, the helmet was improved by incorporating a visor that could be moved and completely cover the face of the knight. In the cuirass we can distinguish among others: the helmet, the breastplate, the back, the skirt, the gauntlets, the leg, etc. This armor weighed between 20 and 30 kilos and it was not an easy operation to put it on, most of the time requiring another person to carry out the operation. Beneath the armor, the knights wore a padded doublet, called a gambeson.
