This item is an original three-layer fabric developed with the motif of the U.S. Air Force flight jacket "MA-1." The three-layer fabric, consisting of nylon twill (surface) + polyester cotton (intermediate layer) + nylon taffeta (back), is very light, and features the soft feel of a bonded material and the vivid rescue orange of the lining. This series is packed with the thorough commitment of Yoshida Kaban craftsmen in every process, from cutting to sewing and parts. There is some peeling of the zipper and staining on the orange parts due to aging, but this adds to the character. The zipper opens and closes without issue. It feels a little stiff. There are no tears. It's still perfectly usable, but I'm selling it because I bought a new one. Thank you for looking.
