A pocket T-shirt made of durable cotton jersey that has been firmly hammered and has little fuzziness. They use a new spinning method called VOLTEX spinning, in which the yarn is spun using a swirling flow of air. The short fibers are blown out by air and each fiber is twisted towards the center of the thread and covered by other fibers. As a result, the inner layer of the yarn has a structure in which the fibers are firmly held, making it difficult for the fibers to move, resulting in a spun yarn with less fluff, so when it is made into a product, it has less fluff, suppresses pilling, and is less likely to fade. The orslow icon, the map of Japan, is embroidered on the back under the collar. The silhouette is a standard shape that is neither slim nor wide.
