I bought this to protect myself from UV rays while riding my bike, but I never ended up wearing it and just left it sitting around, so I'm putting it up for sale. It's made of sturdy fabric, is plain, and the color is beige, so I think it's easy to match with anything. Size: M Head circumference: 55-58cm Brim length: Approximately 8cm / Brim width: Approximately 18.5cm Depth: Approximately 11.5cm 100% cotton The size adjustment belt is inside, so you can adjust it, and the silhouette from the back looks beautiful. Due to the price and to prevent it from losing its shape, I would like to ship it via regular mail (定形外郵便), so thank you for your understanding.
