Dotsume/High-density jersey fabric is an extra-thick material of approximately 11.5 ounces, made of American cotton and knitted by loop-wheel knitting machine. As it is knitted very slowly, each knitting machine can only produce about 30 pcs for T-shirts per day, but it is characterized by its ability to evenly pack the yarn and its resistance to shrinkage and distortion even after repeated wear and washing. This long-sleeved T-shirt is made with ribs as thick as a sweatshirt to match the body fabric, creating a well-balanced overall look. It has the advantages of being non-transparent and sweat stains are less noticeable, and its firmness makes it less likely to cling to the skin, making it comfortable to wear. The neck is made with a binder to increase durability.
