This is a B-11 FLIGHT JACKET worn by the U.S. Army Air Forces (U.S.A.A.F) during World War II. 【Item】 Rare 40s WW2 US Army Authentic B-11 Flight Jacket Made by BEN GREENHOLTZ & CO. B-11 flight jacket of the U.S. ARMY.AIR.FORCE (U.S. Army Air Forces), an early model with adjusters on the sleeves. US AAF 40s The front has a double structure of buttons and a zip, and the zip is a CONMAR ZIP with a "ko" shape stop. The lining is alpaca. The zip is damaged, but I have never felt any inconvenience because of the double button structure. There are some tears and repairs in several places, but I think it is in a condition that you wouldn't believe it's 70-80 years old. This is a recommended item for collectors. As this is a vintage item, please understand that it is sold as-is. There is a feeling of use, but we will reflect that in the price. Actual size (measured flat) Size notation 38 Although it is 38, it is the image of L to XL in Japanese size. *Please note that there may be some errors due to amateur measurements.
