The White Ensign is an ensign flown on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field with the Union Flag in the upper canton. The White Ensign is also flown by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. The flag is made of a durable nylon fabric, and is reinforced on the outer fly to prolong the life of the flag. Made in the USA.
