Type B-10 is a classic jacket of the US Army Air Force. It was officially commissioned in 1943. It is a very representative combat suit of the World War II military uniform. After that, the B-15 series was derived, and the well-known MA1 was finally born. It is the predecessor of MA1. The B-10 was the main flight suit of the War Zone in World War II, and it was a reliable partner for Army pilots. The surface of B-10 is made of fine-grain cotton fabric, with wool blended fleece inside, and the collar is made of fur, which is very warm. The two large pockets on the coat, combined with the domineering large suede collar, have affected countless men's jackets since then.
