What Is a CPO Jacket?
A CPO jacket is a casual woolen men's jacket based on the design of a Navy chief petty officer's jacket. It is styled like a shirt with buttons down the front and on the cuffs.
Sometimes a zipper is included in addition to the button closing. CPO jackets have two chest pockets with buttoned flaps. Around the neck is a pointed shirt collar. The bottom edge has either a straight or shirttail hem. CPO jackets are traditionally hip length. They are found in navy, as well as less traditional colors. The style is convenient to wear with layers to adjust to changing temperatures.
