Recommended for those who want to avoid UV rays and sunlight, and for those who want to wear a hat deeply. A greige casquette. It's thin, so you can wear it even in the hot season. The head circumference is quite large. There is a string for adjustment, and it can be made smaller with Velcro. I purchased it online about six months ago for 2810 yen, but I've only worn it once. After that, I've been storing it at home. Thank you for looking.
