Thank you for viewing. This is a Muji Light Down Jacket. Color: Dark Navy Outer and inner fabric: Nylon Filling: Down 90%, Feather 10% Measurements taken flat: Sleeve length approx. 45cm, body width approx. 56cm, length approx. 59cm. There is a small sheen on the right chest area. It looks like a sheen caused by friction, but it is unclear if it is a stain. I received this as a gift, but it seems okay when worn over thin clothing. However, it felt a bit tight on me when worn over thicker clothing, so I am selling it. It will be compressed and shipped via Posupaketto (Japan Post's postal packet service). Thank you for your understanding regarding this used item.
