GOOD ON / Long-Sleeve Heavy Henley T-Shirt
Inspired by the two-button henley-neck undershirts issued to the U.S. military in the 1980s, this piece translates the original design into a substantial 9 oz heavy jersey fabric.
Made from high-quality American cotton, the fabric combines the structure of a lightweight sweatshirt with just the right amount of thickness. Soft against the skin, it remains comfortable across seasons. The deep hues achieved through pigment dyeing evolve over time, gradually developing a vintage-like character.
Flat seams and a pattern based on the original undershirt ensure a stress-free fit, providing comfort despite the heavyweight construction.

GOOD ON
Founded in Japan with the aim of recreating the toughness and character of classic American-made products, GOOD ON specializes in T-shirts and sweatshirts made from high-quality American cotton. Each piece is designed to grow richer in texture and character the more it is worn.
Built tough for everyday wear
Made from 100% cotton 9oz heavy jersey, this piece has the substantial feel of a lightweight sweatshirt. Firm yet soft against the skin, it delivers the distinctive comfort and quality of premium American cotton.
Meets Strict Quality Standards
GOOD ON uses COTTON U.S.A.–certified fabric, a mark given to products made with at least 50% premium American cotton, recognized worldwide for its quality.
Certified by the Cotton Council International (CCI) and meeting Japan’s stringent quality standards, this cotton delivers long-lasting reliability.
Vintage-Inspired Character
Pigment dyeing creates subtle color variations that accentuate the texture of the fabric and stitching, giving depth and character to the piece. With repeated washing, the color naturally fades, developing a vintage-like patina unique to each garment.
*White is dyed using a reactive dye process, known for its vivid, clean coloration.*
Military-inspired details
The neckline features a classic henley design, accented with oversized cat’s-eye buttons on the placket that add subtle presence to an otherwise minimal look.
Flat seam construction and a carefully calculated pattern provide a smooth, stress-free feel against the skin. Even when layered, the shirt remains comfortable without feeling bulky.
Faithfully recreating the details of the two-button henley undershirts issued to the U.S. military in the 1980s, this piece carries a rugged, military-inspired feel.
Looks good on its own
