Maille - (chainmail)

Maille (chain-mail) - Mail (also maille , often given as chain mail or chain maille , though this is a modern usage) is a type of armour or jewelry that consists of small metal rings linked together in a pattern to form a mesh.

Mail can sometimes be punctured by a spear or shorn by the blow from a heavy axe or sword and its flexibility means that it's wearer is still somewhat vulnerable to blunt weapons. Nevertheless, it was an effective and popular defense for its ability to stop cutting weapons from piercing the skin. - Reference: Wikipedia
