Gambeson
Sympkyn
A gambeson (also known as, or similar to where historic or modern distinctions are made, the acton, aketon, padded jack, pourpoint, paltock, haustement, 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 or pourpointing that produced a padded cloth. They were usually constructed of linen or wool; the stuffing varied, and could be, for example, scrap cloth or horse hair.
