This is a genuine N-3B flight jacket from the 1970s. It was adopted by the US Air Force for extremely cold regions, and its appeal lies in the heavy nylon shell and the warmth of the alpaca lining. The dull luster of the nylon and the unique vintage texture, which you can't experience with current products, are still well-preserved. The fur is also intact, making it a great piece. The size is marked as Medium, but I, who am 180cm tall and weigh 78kg, could wear it with room to spare. There is some tearing on the inside, but it won't be noticeable when worn. I personally think this will be trendy this year. How about getting one before the price goes up? Please feel free to ask if you have any questions, such as for additional photos.
