GOOD ON / KODENSHI Long Sleeve Thermal T-Shirt

GOOD ON
Founded in Japan with the aim of creating T-shirts that embody the toughness and increasingly rich character of classic American-made garments. The brand offers T-shirts, sweatshirts, and more with a focus on high-quality American cotton.

Natural Warmth from U.S. Cotton and KODENSHI
The fabric combines the brand's signature U.S. cotton, known for its durability and soft feel, with KODENSHI, a high-performance material that absorbs far-infrared rays emitted by the body and helps retain warmth.

The textured waffle knit offers a comfortable balance of flexibility and resilience while trapping plenty of air to help maintain natural warmth without overheating.



KODENSHI Fiber for Natural Warmth
KODENSHI fiber is a functional material containing ceramic particles that absorb far-infrared rays emitted by the body, helping retain its natural warmth.

Key Features
・Unlike heat-generating materials, it makes use of the body's own heat to help maintain warmth.
・Helps maintain a comfortable temperature and humidity without excessive heat buildup.
・Helps reduce stuffiness and the chill caused by perspiration, keeping you comfortable throughout the day, even on days with significant temperature differences between indoors and outdoors.

Combined with the air pockets in the waffle knit, KODENSHI fiber helps provide comfortable warmth in cold weather.



Rich Texture from Waffle Fabric and Distinctive Dyeing
P-Natural and P-Black are pigment-dyed, while Black is reactively dyed for a more vivid color. The distinctive texture of the waffle fabric combines with the tonal variations created by the dyeing process, giving each color its own rich character.



The sizing is designed to account for shrinkage caused by garment dyeing. As the garment is sold after its expected shrinkage has already occurred, you can choose your size without having to worry about further shrinkage from washing.





Thoughtful Details Balancing Ruggedness and Comfort
The neckline features a classic crew neck design that blends naturally with a wide range of styles.



Ribbed cuffs provide a secure fit and look great even when the sleeves are pushed up.



The garment features four-needle flatlock stitching, which joins the fabric with flat, low-profile seams. Commonly used in underwear, this sewing technique reduces bulk at the seams for a smoother feel against the skin.



The hem features a neat cut-off finish. Lock stitching helps prevent fraying, combining a relaxed look with lasting durability.





A Relaxed Silhouette with a Refined Look
The body and shoulders offer just the right amount of room, while avoiding excess bulk for a clean, streamlined look. The fit drapes comfortably without clinging too closely to the body, creating a relaxed feel without looking sloppy.



The textured waffle fabric gives the piece enough presence to wear on its own, creating an effortless look with simple styling. It also layers neatly beneath jackets without adding excessive bulk, providing extra warmth while maintaining a clean profile for dependable everyday wear.
