Purchased from the official website. Worn about twice. I think it's in relatively good condition. "WOOL CPO SHIRT" - Made based on the 40's US Navy CPO shirt. Instead of the original, cold-resistant, hard melton material, soft worsted wool is used for a relaxed feel. The buttons are made of buffalo horn. WOOL 100% This twill material is made from Super120's yarn, spun to 1/60, covered with water-soluble vinylon, and woven very loosely. Brown warp threads and charcoal melange weft threads are used, creating a unique color that changes depending on the angle. Stone bio processing and tumbler processing are applied to give it a vintage feel.
