GOOD ON / Heavy Set-in Long Sleeve Pocket T-shirt
The "Heavy Raglan T", which has a particularly high repeat purchase rate among GOOD ON items, has been re-specified with "set-in sleeves" as a special order model for HAKU.
Raglan sleeves tend to give a sporty impression, but by changing to basic set-in sleeves, it has become a versatile piece that matches all styles from casual to beautiful.
Please fully enjoy this T-shirt made of 9 oz. heavy jersey fabric made in the U.S.A., which is very comfortable to wear.
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
Established in Japan with the aim of recreating the toughness and character of vintage American-made garments that age beautifully with wear. The brand focuses on T-shirts and sweatshirts crafted from high-quality American cotton, offering enduring comfort and a rich, lived-in texture that grows better over time.
Built to Last — Everyday Toughness
Crafted from 100% cotton in a substantial 9oz heavy jersey fabric, this T-shirt carries the weight and presence of a light sweatshirt. Durable enough for daily wear, it softens gradually with each wash, molding naturally to the body. Enjoy the full comfort and texture that only premium American cotton can deliver.
Certified Quality
Good On uses “COTTON U.S.A” certified cotton — a mark of trust granted only to products made with over 50% high-grade American cotton recognized worldwide for its superior quality. Certified by the CCI (Cotton Council International), each item also meets Japan’s rigorous quality standards.
Color That Matures with Time
The pigment-dyed finish creates rich tonal variations across seams and fabric surfaces, giving each piece a unique character. With every wash, the color subtly fades and develops a vintage-like patina — an evolving expression of individuality and wear.
*White is finished with a reactive dye process, where ultra-fine pigments penetrate deep into the fabric for a clean, even tone and vibrant color.
The neckline is a moderately fitted crew design. Our exclusive set-in sleeve construction allows natural movement of the shoulders and arms while maintaining a clean silhouette and refined balance. The result is exceptional comfort with an effortlessly polished appearance.
Side slits and a slightly longer back hem provide subtle accents that elevate simple styling.
A Tailored Fit for the Japanese Silhouette
Designed with proportions that suit the Japanese physique — a balanced length and streamlined outline. Over time, the fabric relaxes and conforms naturally to your body, creating a personalized fit unique to the wearer. From the first wear to the hundredth, this piece evolves with you, offering lasting comfort and timeless appeal.

Staff comment
● Staff (165cm / 52kg) Body type: Slim Wearing size: S / M Size S offers a true-to-fit silhouette with sleeves reaching the top of the hands. The length falls around mid-hip, with a comfortable fit across the shoulders and slight room in the body. For a more relaxed look, size M is recommended, providing a looser, easygoing silhouette for everyday comfort. |
● Staff (171cm / 61kg) Body type: Average Wearing size: M / L Size M gives a clean and streamlined look, with sleeves ending at the wrists and a length that slightly reveals the hips. In size L, the fit becomes roomier without looking oversized, allowing for a more relaxed and laid-back appearance. |
● Staff (177cm / 67kg) Body type: Average Wearing size: L / XL Size L provides a comfortable fit without any tightness. The ribbed cuffs keep the sleeves neatly at the wrists, and the hem reaches around the hips. Choosing size XL adds more ease through the body, achieving a relaxed, effortless silhouette. |
● Staff (181cm / 80kg) Body type: Broad build Wearing size: XL A balanced fit—not too large, not too small. The sleeves end naturally at the wrists, and the length falls around halfway over the hips, creating a well-proportioned silhouette. |

Care Instructions | ※Please note that the colours may look different from the real thing depending on your monitor environment.
*Pigment dyeing tends to result in uneven color, especially around the fold lines, creating a characteristic mottled appearance. While there may be some individual variation, please understand this as the unique texture of pigment dyeing. *Due to the nature of garment-dyed products, there may be slight variations in color and size for each item, so please be aware of this in advance. Additionally, the products may have a distinctive used look, slight distortion, fraying, wrinkles at the seams, or unevenness in the knit fabric, all of which are part of the product's character. Enjoy the natural unevenness and rugged feel of the material. |
