I kept it at home. New Era Bucket Hat WarmdArt Brand new, unused Size M/L (approx. 59cm) Color Black Employs WarmdArt, an environmentally friendly and sustainable heat storage insulation material that utilizes sunlight. It absorbs near-infrared rays from renewable solar energy and converts them into heat. As a result, a temperature increase of over 10 degrees Celsius in 10 minutes (compared to standard products) can be expected, according to actual measurements. It can reduce the burden on the skin by absorbing and cutting near-infrared rays, which are harmful to the skin and cannot be prevented by UV protection alone. Due to its high heat storage function, it dries in about half the time compared to regular polyester materials. * The top button is made of plastic to prevent rust when wet. * MICROERA with antibacterial effects is used for the sweatband. The silhouette is a bucket hat, characterized by a silhouette that looks like an overturned bucket. The brim (brim) is attached downwards. I will sell it to someone who wants it. How about it?
