I couldn't find a "My Page" or anything like that, and I've deleted the emails, so I can't provide those. I've also thrown away the tags. I wasn't sure about the fit, so I bought both S and M, and I preferred the fit of the S, so I'm selling this one. It's not down, but it seems like it would be quite warm even in winter. I've included images of the item being worn and the size chart from the website, so please refer to those. I'm open to price negotiations.
