In the early 1940s, with the outbreak of the Pacific War, the U.S. Naval Air Force needed a lightweight flight jacket to adapt to the harsh tropical environment. This " M-421A " was created to meet that very need, and can be called the perfection of a summer flight jacket.

This item is an original vintage manufactured by H.& L. Block based on the **1942 contract "NXsa-5134"**. The design shines with its highly breathable cotton twill body, TALON zippers with U-shaped ends, underarm ventilation holes, and other features that thoroughly pursue practicality on the battlefield. This is a piece of clothing that combines a lightweight silhouette with a sense of beauty unique to the U.S. military. It is a summer jacket for "men who know the real thing" that fits naturally with modern military fashion.

This item is over 80 years old.
There are scratches, light stains, and signs of use around the zipper, but please understand them as part of the vintage product's flavor. There is no big damage to wear. Original TALON zipper also works. There are some stains inside the jacket. Please feel free to contact us for more information regarding sizing and condition. Since this is a used item, it cannot be returned. Please understand.
