Mail armor (Some times called Chain Mail) is a type of armor that consists of small metal rings fashion together to form a mesh, which is then fashioned in to coverings for the various parts of the body.
A mail piece designed to cover the chest is traditionally called a hauberk, haubergeon or byrnie depending on its length. Leggings may be referred to as chausses, Hoods are coifs, and hand items mittons.
Mail is worn by hunters and shamans. From classic WoW through Warlords of Draenor, warriors and paladins wore mail until level 40, where they could then equip plate armor. Hunters and shamans began by wearing leather armor until level 40, where they could switch to mail.
