This is a baseball-style cap with a 6-panel cap body and a slightly longer brim. This is made of the same material as the leather patch that is attached to UES product jeans. The leather is tanned "goatskin" and is shrink processed. The inside of the cap body is protected with black tape on the seams of the panels. The head circumference is made of black herringbone fabric with a sweat band. The back center uses highly elastic rubber. This one does not have lining, but Due to shrinkage caused by sweat from the scalp, only size L is available. The genuine goatskin leather changes over time depending on how often you wear it. The color may become darker due to sunburn, sweat stains, etc. This is a cap that allows you to enjoy the unique characteristics of leather with a very nice atmosphere.
