Wool felt hat. Purchased from Ishihara Shoten, a Western shop in Ueno. Size is 59. Unlike crushable soft hats, this hat uses hard felt. Therefore, it is recommended for those who are particular about authenticity. The shop staff told me it's similar to what real cowboys wear. Purchased in early November. Used it once outdoors. I think the purchase price was around 25,000 yen. Thank you.
