From the Celts of 300 BC to 18th century Asia, mail was one of the most prized items a warrior could own. The Foe of Swords probably derived the name "mail" from the Latin Macula meaning net. This coif features 16 gauge links in the "international" pattern - 4 links through a 5th - common to all European mail. Faithfully copied from examples in museums and private collections, it can be worn with or without a helmet. Outer link diameter of each link is about 7/16”, inner link diameter about 3/8”. We recommend keeping this butted steel mail oiled at all times. Made by Windlass Steelcrafts. Express delivery not available on mail.
