I purchased this at a Wilson authorized dealer last year. The retail price was 8,800 yen. I wore it about 5 or 6 times in the fall of last year, but I no longer wear it, so I am selling it. This is a popular item, and I am also selling it on other flea market sites. It's a thin windbreaker, so I think it's perfect for this time of year. It can also be used as tennis wear.
