In 1941, the U.S. Army introduced the M-41 split suit as an alternative to the Denim Work Suit. This new suit included a herringbone twill jacket, a pair of herringbone twill pants, and a Daisy Mae Hat. The suit is suitable for civil engineering work and is also used as a summer combat uniform.
The suit was issued for a short period of time, from 1941-1942, and was only made for about a year. Therefore, its circulation in the second-hand market is minimal, and it is one of the very rare styles.
M-41 trousers were labeled "SPEC. NO. 6-254", which is the same as the 1941 version of the Khaki pants of the same period, only replaced with color OD3 herringbone twill fabric.
The U.S. Army began mass adopting this herringbone twill fabric after 1941 as a replacement for the denim fabric that faded easily and was difficult to conceal. This marked a significant milestone in the history of U.S. Army clothing.
