This is a 575RD casquette from CPH. Size: M/L The material chosen is thick, rope-dyed katagari fabric. Rope dyeing is a dyeing method used for denim, etc., where cotton yarn is bundled into a rope shape and repeatedly dipped in and pulled out of a dye solution to gradually add color. The cotton yarn gradually dyes from the outside, so the closer you get to the core of the yarn, the lighter the color becomes, and the core remains undyed and white. Fabric woven using this cotton yarn will reveal the white core when the surface is rubbed with use, creating a unique "atari" effect and allowing you to enjoy the aging process. The brim is made soft using a stiffener core, similar to TC. The lining uses "COOL DOTS," an environmentally friendly cool stretch fabric developed by "Komatsu Matere," a world-renowned cutting-edge fabric manufacturer, the same as CPH's standard. The natural material's unique color and rugged texture, which cannot be achieved with TC material, give it a more American casual feel than a mode aesthetic. Also, the product has been washed, so it will quickly conform to your head, which is a nice feature.
