This is a wide-brimmed, foldable hat with a Showa-era design. It's made from umbrella fabric, so it's supposedly all-weather. I'm a little worried that it might get your shoulders wet from dripping rain depending on your shoulder width (^^; It's a rare and interesting item (^∇^) ◎ Size when open Free size (head circumference approx. 60cm) Brim width front and back: 45cm Brim width left and right: approx. 46cm ◎ Size when stored Diameter: 18-19cm Thickness: approx. 1-1.5cm This is a very old item that came out of storage, and it's probably unused. There's a cut in the chin strap that looks like a manufacturing error, but otherwise, it's in good condition. Please forgive any unnoticed deterioration. * It will be packed with recycled materials and sent by post.
