The SHIRT, MAN'S, COTTON SATEEN, OG-107 marked a turning point in US Military Combat Uniforms. Evolving from the Herringbone Twill (HBT) era of WWII, from 1954 the US Army began a transition to a cotton sateen fabric as part of the OG-107 uniform.

Early sateen cotton was developed in the colour tone OG-7, before the famous OG-107 came in to production. OG-107, which derived from the color code Olive Green 107 saw action in the Korean War and became the standard for use both in the United States and on overseas deployment by the beginning of the Vietnam War.

From 1955 to 1964, the Utility shirt was constructed with tubular sleeves and without cuffs, alongside a boxier cut in the style of a jacket. The ‘TYPE III’ model seen here, developed in ‘65 and distributed in ‘66 was the first to be cut in the style of a shirt, with a more tailored body and fitted cuffs.
