This vintage jacket started life off as a WWII CFN-24 Colvinex flight suit. These were popular motorcycle jacket conversions post war, due to the relative impracticality of a full length leather flight suit in civilian life, and due to their ease of conversion, with the front zipper having a separable bottom. It is made from goatskin, with a mouton collar, Conmar zipper, chinstrap, under-collar throat latch and belted waist. The owner of this one opted to cut his off at a 3/4 length, requiring it to also be zipped down from the waist to be put on.
This vintage CFN-24 flight suit was made during WWII from goatskin. It is electrically heated, with Colvinex metal core yarn. It has a zip front, zip fly, and zippers running the length of the legs. These were popular to convert into motorcycle jackets post-war due to the zippers having separable bottoms. One of the zips is Korea-era replacement Talon, the others are all WWII manufacture. There are electrical leads on the chest, at the waist and at the wrists to hook to heated gloves. It has a belted waist and patch pockets on the thighs.
