Heavy Hauberk is a Armor in Kingdom Come: Deliverance.
"Chainmail coats and vests are made from small metal rings linked together into a mesh. They differ in the size and shape of the rings as well as the linking system. The rings are usually riveted closed. Chainmail provides good protection against slashing, but can be pierced fairly easily and without a layer of padding provides almost no defence against blunt, crushing blows."
