Thank you for viewing. I purchased this at a shop called Crazy Ink in Americamura, Osaka, when I traveled there. It's a hat that eyden and Watson wore, and the shop is only in Osaka. It was a limited-edition item and very popular, so when I bought it, there were only three in stock. I've worn it about twice! I haven't sweated in it! Size: You can adjust the size with the adjuster at the back! Color: Brown Brand: Crazy Ink
