I've cut off the tag, so I don't have the details. The sixth photo shows where the tag was cut off, not fraying. This item was used by a family member who usually wears standard men's hat sizes. I am selling it due to a change in hobbies. The longest part of the brim was 9.4 centimeters. The fabric seems to be breathable, suitable for summer. It generally looks clean, but there is some discoloration that is noticeable upon close inspection. Please consider this item as used and understand its condition before purchasing.
