Short green nylon jacket featuring two front slash pockets with snap closures and two internal slash pockets. It has a green wool ribbed collar, cuffs, and hem, showing some wear with holes. The left sleeve includes a zipped pen pocket with a leather puller. The jacket fastens with a 1952 metal Crown zip, alongside a zig-zag stitch internal placket on the right side. Faded remnants of the US Air Force wings and star insignia are visible on the left shoulder sleeve.

The jacket includes back shoulder darts and two front snap-closure tabs under the arms, designed to secure headset and microphone wiring leads and a heavy parachute harness. A nylon tab sewn onto the left chest allows the attachment of an oxygen mask retainer clip. These design features were later omitted in the MA-1 flight jacket model.
