The duffle coat owes its popularity to the British Royal Navy, who issued a camel-coloured variant of it as an item of warm clothing duringWorld War I. The design of the coat was modified slightly and widely issued during World War II. In the Navy, it was refered to as a “convoy coat”. Field Marshal Montgomery was a famous wearer of the coat, as a means of identifying himself with his troops, leading to another nickname, “Monty coat”. Large stocks of post-war military surplus coats available at reasonable prices to the general public meant that these coats became a ubiquitous and popular item of clothing in the 1950s and 1960s. The British firm Gloverall purchased surplus military supply of coats after World War II and in 1954 started producing their own version of the duffle coat and continue to do so today.
