Marked as M, but the fit is quite snug. I usually wear a size M and have some room, but this M felt like a perfect fit. Shoulder width: 43cm (measured to the sleeve cuff seam) Body width: 55cm Front length: 56-57cm, Back length: 64cm Measurements are approximate. Thank you. Snow Peak Jacket jk-17au004 Originally priced at 40,000-50,000 yen, so it's a great value. Fire Resistance FR Down Jacket There are some minor scuffs and fading, but it's in relatively good condition as it hasn't been worn much. It looks more compact and slim than a regular down jacket, making it easy for women to wear. Features pockets on both sides, arms, and chest. Zippers included. Color: Black
