This is the Nishikawa Arctic Down from nanouniverse. As shown in the third photo from the left, there is a slight whitening on the right collar, but otherwise, there are no noticeable stains and it is in beautiful condition. I purchased it on zozotown and only wore it for one season. Product Overview: Introducing a stylish, military-like down from Nishikawa Down.
