Worn by foot soldiers, archers, crossbowmen, pikemen, and men-at-arms throughout Europe in the Early and Late Middle Ages, this rather simple helmet in the shape of a wide-brimmed hat owes its name to its resemblance to a pot (originally called kettle).
Although kettle hats existed in many variations, they all shared the same main feature: a wide brim that offered good protection, not only against downward sword blows, but also against hails of arrows or other projectiles fired or thrown from up. This highly protective design, which also did not impair the wearer's sight, hearing or breathing, proved useful during sieges and massed infantry battles, and contributed greatly to the enduring popularity of this type of helmet.
