All wool 1950 Air Force issue flying shirt size large... though it should be classified as a light jacket. Very similar in style to the modern Filson Mackinaw. The wool on this thing is dense and still retains a few of the original AF stamps.. It is in very good shape with only one tiny repair on the back (note in photos if you can find it). $150 plus shipping. Measurements: Shoulder to shoulder (across the back): 20" Chest (pit to pit): 24" Sleeve (shoulder to wrist): 25" Down Back (from collar to bottom):29" Let me know if you have any questions.
