Gambeson

A gambeson (or aketon or padded jack or arming doublet) is a padded defensive jacket, worn as armour separately, or combined with mail or plate armour. Gambesons were produced with a sewing technique called quilting. Usually constructed of linen or wool, the stuffing varied, and could be for example scrap cloth or horse hair. During the 14th century, illustrations usually show buttons or laces up the front.
