COSTA GIOMA This is a 100% wool shirt with a front zipper. My niece bought it to wear while hiking. Recently, there are various synthetic fibers available with functions like moisture-wicking and heat generation, but apparently, wool is still the best for inner layers when you sweat while hiking. She mentioned that even in winter, it's thin yet soft and warm as an inner layer. She wore it about 4-5 times, then home-cleaned it (using a wool-specific delicate detergent) and stored it. There are almost no pills, and it's in beautiful condition. It seems she outgrew it, and I received it, but unfortunately, it's a little too small for me (lol). The manufacturer, COSTA GIOMA, is apparently also famous for high-end cashmere products and makes wool products with a focus on texture. I tried it on, and even for me, who has sensitive skin due to atopic dermatitis, it wasn't itchy (personal opinion). It's thin, so it can be worn in three seasons, excluding mid-summer. I'm offering it to anyone interested. Size (flat measurements) Width: approx. 54cm Shoulder width: approx. 39cm Sleeve length: approx. 56cm Length: approx. 58cm Please excuse any errors due to amateur measurements. There is no size label, but I believe it corresponds to a size L. If you have any questions, I'm happy to provide additional photos. Please feel free to ask. It will be shipped in a waterproof bag, etc. The shipping method may change between "Rakuraku Mercari便" and "Yuyu Mercari便".
