This vintage jacket is made from the best leather there is for clothing - goatskin. It is as soft and pliable as the day I bought it some years ago. The lining is shearling lambskin, the collar is mouton lambskin, and the trim (cuffs and hem) is 100% wool. the sleeves have quilted linings. Measurement armpit to armpit is 25.5 inches implying a 51" chest. The shearling lambskin takes up considerable space inside. Length is 26.5", sleeves are 28". Zipper is heavy brass by Talon. NWOT!
