Disruptive Pattern Material or DPM is the commonly used name of a camouflage pattern used by the British Armed Forces as well as many other armies worldwide, particularly in the former British colonies. This pattern originated around the 1960's until it was phased out around 2016 and a new multi- terrain pattern was produced. These cotton combat pants are great for everyday wear and in any season! The pants have an adjustable waist for multiple sizing, zipper fly, button waist closure.åÊ The pants also have two side hand pockets and cargo pockets as well. Wear a light thermal layer underneath for the colder days or roll the pants up and wear on the beach!
