This is the iconic Type A-3 Mechanic Cap, a classic work cap issued to ground crew soldiers—including aircraft mechanics—in the U.S. Army Air Forces (USAAF) during World War II. It is a size 7 1/4, which is approximately 59. Caps in this wearable size are quite rare.
As one of the iconic caps of the 1940s U.S. military, its design—which pursued practicality to the utmost—had a significant influence on subsequent workwear and American casual fashion. Even today, it remains extremely popular among vintage caps and is a classic that many brands adopt as a design inspiration.
Its most distinctive feature is the extra-long brim. While it can be worn normally, the brim can also be flipped up, providing a practical design that allows for an instant adjustment to ensure forward visibility during aircraft maintenance or similar situations. It is a design brimming with functional beauty, created specifically as a work cap.
The fabric is made of highly durable HBT (herringbone twill). Designed with the aircraft maintenance environment in mind—where exposure to oil and dirt is inevitable—it was engineered to withstand repeated washing, making it a highly advanced specification for its time.While offering the performance expected of a practical item, the beautiful herringbone weave allows you to fully appreciate the unique charm of vintage fabric.
The Type A-3 was adopted not only by the Air Force but also by other branches of the military under different names, a testament to its high level of craftsmanship. However, the USAAF version is truly special and remains an indispensable part of any discussion of World War II-era Air Force equipment.
This particular cap was manufactured in the early 1940s and is a rare find, with its size tag, manufacturer’s tag, and USAAF stamp all preserved in excellent condition. Furthermore, at size 7 1/4—a “golden size” that fits Japanese people well—it offers the significant appeal of being not just a collector’s item but something you can actually enjoy wearing.
It remains in excellent condition, appearing to be virtually unused, and opportunities to find a Type A-3 in such good condition are becoming increasingly rare with each passing year. As a cap that epitomizes authentic World War II-era equipment, this is a masterpiece we can confidently recommend for both collecting and everyday wear.
