Bearskin hats are tall, fur hats traditionally worn by the British Army and other military units during ceremonial events. Made from the fur of the Canadian black bear, these hats are designed to be both striking and functional, providing warmth and a distinctive appearance. Typically, bearskin hats stand about 18 inches tall and are worn by Grenadier Guards and other regiments. They are often associated with the Changing of the Guard ceremony at Buckingham Palace, where soldiers wear these iconic hats as part of their formal uniforms.
