Thank you for viewing. This is a SUNDAY AFTERNOONS Adventure Hat. It's a hat that will be a great help in outdoor scenes such as festivals, camping, and trekking. Of course, I think it can be used in the city as well. Sunday Afternoons is an American hat manufacturer that has been making hats for about 20 years. Founded in 1992 with blankets for outdoor use. In 1996, they developed the "Adventure Hat" and obtained a US patent. And, it has been established as a hat brand with high-quality UV cut function of UPF50+ as standard. Although it is new and unused, please note that it is a home storage item. The size is marked MEDIUM (inner circumference about 54cm). There is a rubber part, so there is some leeway. Please understand the error as it is amateur measurement. Please refrain from purchasing if you are nervous as it is used clothing. If you have any concerns about the condition, please contact us from the comment section before purchasing. There may be parts that I have overlooked. Shipping will be folded small as shown in the 15th photo. Please note that the brim will be folded as shown in the 16th photo. All packaging materials will be recycled. The person who purchased first will be given priority even during comments. Thank you.
