The miner's cap (German: Fahrhaube) is part of the traditional miner's costume. It consists of a white material (linen) and served in the Middle Ages to protect the miner when descending below ground (unter Tage). Later it was replaced by the miner's hat (Fahrhut or Schachthut), from which the leather cap or helmet were developed and subsequently today's mining helmets.
