Aventail

A skirt of mail attached to a bascinet or armet during the 14th and 15th centuries. It defends the neck from attack, usually hanging to at least 1" below the shoulder point for bascinets. Generally it was attached to a leather cuff that wrapped around the base of the bascinet and up the cheeks, which was pierced with holes and laced to the helmet through vervelles .
