I used this a few times for mountain climbing, but it has been stored in my closet at home since then. Please understand that this is a used item. Mesh Basic Cap ¥9,000 Black hat with mesh panels and a drawstring. Excellent breathability, perfect for the outdoors. The brim and forehead area of the cap use Toray's Stunner®, a 100% nylon material that is water-repellent, windproof, and breathable. It prevents discomfort from sweating while protecting against rain and wind, and also has excellent durable water-repellent properties. In addition to a natural appearance similar to a cotton blend despite being a synthetic fiber, the coating applied to the back creates a moderate firmness. - Brand: RIDGE MOUNTAIN GEAR - Color: Black - Design: With mesh panels - Adjustment: With drawstring - Inner structure: Mesh lining Spec Material: Body: 100% nylon, Mesh: 100% nylon, Sweatband: 100% polyester Size: One size fits all, Depth approx. 17.5cm (when laid flat), Brim length approx. 6cm, Head circumference approx. 60cm (adjustable with elastic) *There may be a margin of error of approximately ±1cm in the finished product size.
