The term "duck hunter" camouflage is generally applied to a pattern having large, irregular spots in several colors on a solid background. Duck hunter patterns trace their origins to the US M1942 spot pattern camouflage of the Second World War, worn primarily in the Pacific Theater of Operations. Variations of the original pattern were reproduced by numerous American and foreign companies from the 1960s well into the 1990s and were marketed as hunting apparel for sportsmen. The popularity among duck hunters was strong enough that the nickname has stuck with the pattern even though most contemporary sportsmen probably opt for different types of camouflage today. This style of camouflage is also often called "spot" or "duck hunter spot." Many nations have adopted variations of the "duck hunter" pattern, although the design is considered somewhat archaic and has generally died out of usage except with a few nations.
