This is the popular Arc'teryx "Sinsolo Hat." It's a lightweight and breathable bucket hat, suitable for outdoor activities, festivals, and everyday wear. Currently, it's not widely available in Japan, and the rare gray color is particularly popular. Also, most currently released versions have a chin strap, making this "no-strap" version unusual. The condition is clean, with no noticeable issues. It's being offered at a low price, so it's first-come, first-served.
