In the summer of 1941, following selection by the Army, new work uniforms were issued made of cotton herringbone twill (HBT). Although they replaced the blue denim uniforms, they were also called "dungarees". These were sage green in color, a shade used only by the Marines, a lighter color green than the Army OD #7. Shirts had USMC over the Eagle, Globe, and Anchor stenciled on the left breast pocket of the garment.
