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 in the Japanese climate. Because it has a high neck, I think it can also be worn under a coat as an inner down. According to the staff, it's a prototype because there's no brand logo on the part where the Y-3 logo is usually placed. If you like Yohji Yamamoto or ADIDAS, please consider it! Size: M Width under the armpits: Approximately 54cm, Shoulder width: Unknown because there are no stitches (around 50cm), Length: Approximately 67cm Color: Black This jacket was purchased used. I've worn it once or twice, but please consider it with an understanding of used clothing, such as some signs of wear and tear and aging.
