Size 49. I recently bought this hat because the sunlight has been strong lately, and I was looking for a hat with a sunshade. I have several hats, so I haven't used this one very often. There's a faint stain on the top of the hat, but it's not very noticeable. I think I bought it at Moujonjon for around 3000 yen. Spring has the strongest UV rays, so I think you can use it from now through the summer. I'm selling it at a low price, so please consider it.
