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.
