This is our CAMO HQ version of the Snow MARPAT pattern. The oriiginal used by the U.s. Marines was created by Hyperstealth in 2006 by adding a subtle digital grey to the solid white overwhites to mimic shadows in the snow. The pattern was trialed at January 2007 at the Mountain Warfare Training Center in Bridgeport, California and at Elmendorf Air Force Base in Alaska. This pattern was still current (as of September 2022) in use for winter training.
