The “Heavy Raglan T” is one of our most popular items, with the highest repeat purchase rate among our brands. This time, we have created a special order model with a set-in sleeve design, based on our popular classic T-shirt.
The set-in sleeves make it versatile for a wide range of styles. Designed to complement everything from casual to smart-casual looks, this T-shirt is made from American-made 9-ounce heavy jersey for a substantial feel. Enjoy the full comfort of this premium T-shirt.
Additionally, we offer a special color exclusive to ROCOCO: “P.R. Khaki.” This rich, earthy shade is a unique blend of black and sage, adding a sophisticated touch to any outfit.
Note on Sizing:
GOOD ON T-shirts tend to run small due to their Japan-specific sizing.
We recommend choosing one size up for a comfortable, modern fit.






















GOOD ON
Founded in Japan with the aim of recreating the durable, character-rich T-shirts of classic American craftsmanship. The brand offers T-shirts and sweatshirts made with a focus on high-quality American cotton.


Premium American Cotton, Certified for Quality
Good On uses "COTTON U.S.A" certified cotton. This mark is given only to products that contain over 50% high-quality American cotton recognized worldwide.
Certified by the CCI (Cotton Council International), this label is a mark of trust granted only to products that meet Japan’s stringent quality standards.
Hefty Yet Comfortable Fabric
This 9-ounce T-shirt fabric lets you fully experience the comfort of quality American cotton. Though substantial in weight, it gradually molds to your body with each wear, gaining a refined texture and depth over time.

One-of-a-Kind Character from Pigment Dyeing
The pigment dyeing process highlights the highs and lows of the fabric and seams, creating a richly textured finish that’s unique to each piece.
With every wash, the color gently fades from the surface, adding even more depth and charm. Over time, it takes on the feel of a well-worn vintage favorite.
*Note: White color options are dyed using reactive dye, where fine dye particles penetrate the fabric deeply. This method enhances color while preserving the natural texture of the fabric.


Reinforced Stitching with Thoughtful Details
Built with sturdy stitching to support the dense fabric, preventing stretching and distortion over time.
The side vents and elongated back hem add a subtle design touch. The side slits also visually slim the waist area, enhancing the overall silhouette.


Tailored to Fit the Japanese Body
The silhouette offers a clean, streamlined look. Every detail—from the arm and underarm lines to the overall length—has been carefully adjusted for a better fit on Japanese body types.
Additionally, the fabric relaxes and conforms to your body the more you wear it. Enjoy how it evolves to fit you better over time.

Staff comment
●Staff (165cm / 52kg) Build: Slim Wearing: Size M The length reaches about halfway down the hips. The shoulders fit just right, and the body has a moderate amount of room. The sleeve length falls above the elbows. If you prefer a snug fit, sizing down could work well. |

●Staff (177cm / 67kg) Build: Average Wearing: Size L The length falls around the middle of the hips with a roomy fit. Shoulders are just right, and sleeves fall above the elbows. Size L offers a relaxed feel, but if you prefer a looser fit, XL is also a great option. |
●Staff (181cm / 80kg) Build: Broad Wearing: Size XL Worn comfortably with no tightness. The length covers about half the hips. Shoulders fit just right, and the body has a roomy feel. The heavyweight fabric feels substantial yet soft and comfortable against the skin. |
