Our Butted Steel Coif is the least expensive mail we've ever offered! Mail was celebrated in poetry and the sagas, being referred to as the (Shirt of Odin), the Byrnie, hard and hand linked and the Net of Battle. This coif features 1.5mm 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 inches, inner link diameter about 3/8 inches. We recommend keeping this butted steel mail oiled at all times.
