This is the KIJIMA TAKAYUKI POLY COTTON ELASTIC BACK 6PANEL CAP. I purchased it at the Daikanyama flagship store, but I'm selling it because I haven't had a chance to wear it. I've only worn it once, so it's practically new. The material is quick-drying and shape-retaining, so it can be washed (confirmed by the store staff). The size is 2 (see photo 4 for details). Please consider it. The following is from the official website: - Recycled polyester x cotton twill stretch - Uses CrispyX (crispy cloth) with moisture absorption, quick-drying properties, and shape retention - Smooth texture and refreshing linen-like coolness - UV shielding rate of 98% - Puffiness due to puckering - Elastic back fit - With S loop - Uses recycled visor core - Hand washable
