We love a translation from Japanese! We would add that these sweats are 100% Cotton, absolutely fantastic, and we recommend purchasing a size up. 

A sweatshirt that has evolved from a wool knit material to a cotton material with a looped brushed back, and has evolved as a "shirt that absorbs sweat" as a daily wear for Americans. The military and military academies, who practice hard training on a daily basis, quickly took notice, and even base stores scattered throughout the United States began to sell it. The material has a unique flexibility because it uses a tubular loop knitting machine that is woven with uneven tension just like at the time. The stitching is done with a 4-needle flat seamer suitable for underwear, etc., and the V-shaped gusset is sewn with rib material on top of the body, commonly known as "beating V".
