Type A-1

A timeless precursor to the iconic A-2, the Type A-1 Flight Jacket stands as one of the earliest expressions of American military aviation style. Standardized by the U.S. Army Air Corps in 1927 and remaining in service well into the Second World War, the A-1 embodies the transition from civilian elegance to functional military design—its origins tracing back to refined 1920s summer jackets, believed to be influenced by Italian tailoring.

The enduring influence of the A-1 is unmistakable, its clean, sophisticated silhouette continuing to inspire modern jacket design across the world.

Cut with a slim, elegant profile, the A-1 is traditionally crafted in supple capeskin, a lightweight leather prized for its exceptional comfort and effortless wear. Alternative leathers are also available, allowing for a personalized expression of this historic design.

Signature details include finely knitted wool cuffs, waistband, and collar, a pure cotton lining, and horn buttons in rich coffee or honey tones—each element selected to reflect both authenticity and understated refinement.

Our primary pattern is derived from the esteemed Gordon & Ferguson interpretation, while additional period-correct variations are offered to reflect the diversity seen in archival photography of the era.

Though presented through simple line drawings, each jacket is brought to life with immaculate craftsmanship and uncompromising attention to detail, ensuring that every piece bearing our name meets the highest standards of Bill Kelso Mfg. excellence.

This is more than a garment—it is a refined expression of early aviation heritage, designed to be worn, appreciated, and treasured for a lifetime.
