A gambeson is a padded defensive garment worn in the Middle Ages, typically made from layers of fabric stuffed with materials like wool or linen. It was designed to absorb and distribute the impact of blows from weapons, making it an essential piece of armor for soldiers and knights. The gambeson could be worn alone or under other armor, such as chainmail or plate armor, providing extra protection and comfort. These garments were often tailored to fit the wearer and could be fastened with laces or buttons. The use of a gambeson was common among various cultures, including the European knights and Samurai warriors, highlighting its importance in historical combat.
