Vambraces (French: avant-bras, sometimes known as lower cannons in the Middle Ages) or forearm guards are tubular or gutter defences for the forearm worn as part of a suit of plate armour that were often connected to gauntlets. Vambraces may be worn with or without separate couters in a full suit of medieval armour.
