One of our favourite camo patterns, the four-colour U.S. Woodland, is now used in gear being produced by Helikon-Tex... "Along with the iconic BDU (Battle Dress Uniform), the U.S. Woodland camouflage pattern was introduced in 1981 and used for almost 20 years by the US military forces. Known in short as M81, this four-color camo marks the change in the battle environment from close-range operations, like in Vietnam, to modern, long-range ones."
