An aventail or camail is a flexible curtain of chainmail on a helmet, that extens to cover the neck and shoulders. The mail could be removed for cleaning or storage, and attached to the helm through use of a leather cord that was threaded through brass rings at the edge of the helm. Aventails were most commonly seen on bascinets in the 14th century and served as a replacement for a chainmail coif. Some aventails were decorated with edging in brass or bronze links, or dagged edges. By the late 15th century, the Aventail had replaced the chainmail coif completely. Only those who were poor or who were collectors of the sort had a chainmail coif.
