Authentic reproduction of the first Type Utility Herringbone USMC trousers. The US Marine Corps has adopted the Herringbone Twill Utility Trousers since 1941. The silhouette is a classic straight silhouette called «navy cut» that has been adopted by the Navy for a long time. The front pocket is a patch pocket only for the early 1941 model, and since then it has become a slash pocket specification found in general trousers. The size of the front pocket is the same on the left and right, and the belt loop hangs only on the left pocket because the front-aligned notch is the center.
