A camail is a flexible strip of mail hung from the bottom of a helm, intended to protect the neck and shoulders; it is also called an “aventail”. The camail is a period charge, used as the badge of George, Duke of Clarence, d.1478 (possibly as a cant on “gorget”), and then as the badge of his grandson, Henry Pole, Baron Montague, d.1539 [Siddons II.1 124].
The camail is fesswise by default. The illustration is taken from Montague’s standard, c.1510 [Walden 179]. See also armor.
The King of the East bears as a badge: A camail argent.
Kristoff Karlsson bears: Vert, a camail and in chief a pair of smith’s tongs fesswise Or.
