I believe this is a collaboration down jacket between Back Number and Maruhachi. It's a dark navy, size M. In my opinion, since Maruhachi is a cotton manufacturer, it's surprisingly warm from the moment you put it on. It also looks sleek and is incredibly stylish when worn. The hood is detachable with a zipper. There's some stitching on the underside of the right sleeve where it was frayed; I've included a picture. It's completely unnoticeable, but I've mentioned it just in case. This is a used item, so I will only sell it to those who understand and accept the condition as shown in the pictures. I look forward to your purchase.
