What is a CPO jacket?A wool shirt jacket issued to Chief Petty Officers in the U.S. Navy from the 1930s
The CPO jacket is based on the thick wool work shirt issued to Chief Petty Officers of the U.S. Navy, called Chief Petty Officers, beginning in the 1930s. The basic specifications include dark blue melton wool, large buttons that can be easily handled with gloves, flap pockets on the chest, and a boxy silhouette designed to be worn over heavy knitwear. Early models had only one pocket on the left chest, which became the origin of the term ” CPO shirt ” in later years.
In the postwar period, two-pocketed jackets were introduced for civilian use, and these became known as ” CPO jackets ” due to their versatility as everyday wear. The CPO jacket is characterized by the fact that it can be interpreted as either a shirt or a jacket, depending on the thickness of the wool and whether it is lined or not, and even today it is often referred to as a “shirt,” “jacket,” or “overshirt. The shirt is also known as a “shirt,” “jacket,” or “overshirt.
