NEXTRAVELER check shirt, size XS. I think it's for a small man or a woman. The check color is dark navy. Only tried on, but I washed it at home before listing it. The following is an explanation from the website: We received many requests from "white shirt" and "blue shirt" users, such as "I want a lighter shirt" and "I want a shirt that doesn't show dirt as much," so we spent two years developing the "check shirt," the first patterned item in the NEXTTRAVELER TOOLS line. Made with Egyptian Giza cotton, one of the three most durable and rare cottons in the world, and gingham check from "Banshu Somen-ori," which is famous for providing to mega-maisons. Using fine count 100/2 yarn, the glossy surface and supple feel are very pleasant, and we have also succeeded in making it lightweight. The "check shirt" is only 170g, compared to about 340g for the "white shirt" and "blue shirt"! When folded in half and compressed, it is about half the thickness of an iPhone 11 Pro Max (just over 4mm!), and it is also easy to care for, so it is wrinkle-resistant.
