Y-3 Y's (Y-3) Prototype Down Jacket Nylon Jacket Outerwear High Neck Double Zip Mode This is a Y-3 down jacket purchased from a used clothing store in Shinsaibashi. Although it's a down jacket, it's not too thick, so I think it's easy to wear even in the Japanese climate. Because it has a high neck, I think it can also be worn as an inner down under a coat. According to the staff, it's a prototype because there's no logo where the Y-3 brand logo is usually placed. If you like Yohji Yamamoto or ADIDAS, please consider it! Size: M Width under the armpits: about 54cm, Shoulder width: unknown because there are no stitches (around 50cm), Length: about 67cm Color: Black This jacket was purchased as used clothing. I've worn it once or twice, but please consider it with an understanding of the used condition, such as some signs of wear and tear and aging.
