The couter was added to the hauberk to better protect the elbows, and splinted armour and the coat of plates provided increased protection for other areas.
Depending on their fitness, a fighter wearing hauberk and chausses can run, lie, stand up, jump, do somersaults (or even cartwheels), and even swim wearing full armour.
This imaginary armor set consists of mail hauberk, an open-faced helmet with a nasal (nose protection), and boiled leather armor about the arms and legs.
