This is a flight jacket from the French Air Force, of an unknown era. The jacket material is likely a blend of synthetic fibers and cotton. The approximate size is: width 55cm, length 72cm, sleeve length 58cm, shoulder width 50cm. It's a type with a longer length than standard flight jackets. The boa lining is removable. There are no particularly noticeable stains or damage, but the elastic in the waist and arm ribbing is stretched. There is a drawstring at the waist, allowing you to cinch it.
