【Sun Barrier 100】 【Completely Blackout】 Purchased in 2023 at the official store in Okamot, Kobe, Hyogo Prefecture. Worn a few times, home cleaned. There are no noticeable stains, but there is some wear and tear. The official statement is that the blackout effect lasts as long as there are no tears, so I believe the effect remains unchanged. This is a completely blackout hat that cuts 100% of UV rays, 100% of infrared rays, and 100% of visible light. It's a hat with a 11cm brim. It comes with a removable hat strap with adjustable length. Retail price: 8,200 yen (tax included 9,020 yen) The size is M (approx. 57.5cm), but it can be adjusted to be about 3cm smaller with the Velcro adjuster inside the hat, so it can also be used by those who wear S size. (The M size is not indicated on the hat.)
