Thermal fabric with heat retention properties

Fabric is tailored from 100% cotton. The thermal fabric is made from durable and comfortable USA cotton, knitted into a waffle shape with moderate elasticity, stretchiness, and warmth by excellent Japanese craftsmen's techniques. The four-needle flat seamer gives it a gentle and comfortable feel against the skin.

Globally acclaimed high quality American cotton
GOOD ON uses "COTTON U.S.A.". The "COTTON U.S.A." mark is a trustworthy mark that is given to products that use 50% or more of the world-renowned high-quality U.S. cotton, certified by the CCI International Cotton Council, and only to products that have passed the strict quality standards of Japan.



"Pigment Dye" that gets more textured with each wearThe pigment-dyed color, in which shades of color stand out in the waffle fabric's distinctive unevenness, is characterized by a look that is uniquely appealing. The color gradually fades from the surface with each washing, further increasing the texture, so the longer you use it, the more it will look like a high-quality vintage item.








Fits the Japanese body shape and way of wearing
GOOD ON is sewn with optimal dimensions and cutting in all areas, including shoulder width, length, sleeve length, cuffs, and armholes. The design & pattern designed to fit and become a part of the body without discomfort when worn is the biggest reason for its long-lasting popularity.
