This is a warm blouson with padding (stuffing) inside. Synthetic fibers such as polyester are often used instead of down for the padding to enhance heat retention, and it is relatively easy to care for. I bought this this year, but it's too big even in size M, so I'm selling it unused. * Padded blouson (shorter length) Width: 62cm, Shoulder width: 46cm Length: 61cm, Sleeve length: 65cm Color: Charcoal gray Weight: 630g Thank you for looking.
