Mainly using silk and ceramic charcoal-dyed organic cotton, knitted without sewing, "belly wrap" and "spats (cover pants)" are integrated to prevent the cold. Normally, innerwear is knitted from threads, cut out with a mold, and then sewn using a sewing machine. This product is made directly from thread and is made without sewing. The fabric stretches well, so you can wear it without stress even if the size around the stomach and waist are different. The absence of rubber seams prevents the skin from rubbing and makes it difficult to get marks. In addition, it is characterized by the fact that the seam lines do not resonate. It is made of 91% cotton and silk, so it can be used safely even by people with sensitive skin.
