U.S. Issue Multicam Trouser. Material content of Rayon/Para-aramid/Nylon Ripstop.Multicam is a single camo pattern designed to help blend in to various environments, seasons and times of the day. This is primarily done by the absorption and reflection of lighting. Since only a very small portion of the human eye recognizes color, the brain does a lot of filling in for the eye. Multicam helps the observer to see the pattern as the background. The MultiCam Trouser is constructed to the same specifications as the ACU trouser and features a leg cuff with front closure tie which allows for more comfortable closure on the outside of the boot collar. Also features knee pouches with hook and loop closure, bellowed calf-storage pocket, and two-tilted cargo pockets.
