This is a French Air Force utility jacket that I purchased from a specialty store. The collar is made of corduroy fabric, inspired by a Barbour jacket, and is removable. ∼The following is a quote from the website∼ This jacket, made with cotton twill that evokes the atmosphere of the 70s and 80s, has a good texture of cotton fabric unique to older years, a smooth feel, excellent durability, and a breathable material. It features a front design with a zipper closure and two pockets with Velcro closures. Each pocket has a pen holder on the zipper side. Velcro is provided on the upper part of the chest pocket, which adds an accent to the design. Darts are inserted towards the cuffs, creating a three-dimensional silhouette, and it does not have epaulettes on the shoulders, so it is a design that can be worn by many people. The cuffs can be opened and closed with Velcro and buttons. Rolling up the sleeves creates a lighter look. The armholes are not too wide, making it a well-balanced piece. This jacket will fade nicely with wear, further enhancing its atmosphere. The simple and basic design is versatile for a wide range of styling, and it is a rare French Air Force jacket that is hard to come by.
