This is a FOX cotton T-shirt knitted with an old-fashioned loop knitting machine in Wakayama Prefecture, where only a half-turn can be woven in a day. The hanging machine does not add unnecessary tension to the yarn, it slowly knits it up, and even after the knitting is finished, the fabric is not wound up and stored under the knitting machine. Therefore, it is characterized by being plump and soft, thick but light. As the function of FOX cotton, due to the original hollowness of the cotton fiber, it has a high air content rate, excellent quick-drying properties, and excellent heat retention. It also has features such as blocking 95% of UV rays.
