U.S. National Air Force Insignia 1943 Ballcap, Navy
In 1943, the U.S. Airforce conducted experiments showing that at a distance, shapes were more important than colors when identifying aircraft. Soon after, bars were added to the roundel with an Insignia Red outline. This gave the U.S. the first bared insignia, "Insignia Specification Number AN-1-9a". Embroidered on the front of a mineral-washed ball cap, it was a revolutionary design move by the U.S. military. The back embroidery is a F4U Corsair. A premium leather strap and metal clasp is used to adjust size and creates a hat that is top-shelf. Make sure you are wearing a Revival™ ball cap.
