This is a Sweet Years down jacket. I bought it for around 53,000 yen and wore it 2-3 times. It has a zipper and the sleeves can be detached to be worn as a down vest. There is one issue: I can't reattach the sleeves after removing them. I think it's probably because I'm not very good with my hands, but someone with more dexterity might be able to attach them properly. Because of this, I'm selling it at a slightly lower price. It has drawcords at the neck and hem, so you can tighten them. Measurements are: length 73cm, width 65cm, shoulder width 51cm, sleeve length 70cm. The size is XL. The color is white.
