Thank you for viewing this Iron Heart denim shirt (jacket). The size is S. The fabric is very thick, including the inner lining. This Iron Heart denim shirt is unique, with denim fabric on the outside and wool, polyester, rayon, and nylon on the inside. It's a great piece that can be worn as either a shirt or a jacket. It has four pockets on the outside and one on the lining, so you can carry a lot of things, making it very useful and eliminating the need for a bag. I haven't worn it much since I bought it, so it's in good condition. Although it's labeled as size S, it's made as a jacket, and I, who am 174cm tall, can wear it normally, so I think it's actually about a size M.
