Jackman Dotsume Rib T-Shirt Dirty Dirty Base
The Jackman Dotsume Rib T-Shirt blends Japanese craftsmanship with vintage American sportswear style. Made from ultra-dense cotton knit, it offers a structured, sweatshirt-like silhouette with a comfortable, breathable feel. Its slightly small Japanese sizing makes it ideal to size up for a relaxed, boxy fit.

The Jackman Dotsume Rib Tee draws inspiration from vintage short sleeved sweatshirts. Crafted in Japan from original 11.5oz Dotsume-Tenjiku fabric, it’s made using high-quality American cotton and woven with double the thread countof a standard tee. This ultra-dense knit delivers a uniquely firm yet comfortable texture that softens with wear while retaining its structure.
Engineered for long-term durability, every element—from the fabric to the stitching—reflects Jackman’s commitment to quality. The use of loop-wheel knitting machines ensures a consistent, high-density finish that balances toughness with refined aesthetics.
The ribbing matches the thickness of the main body fabric, resulting in a structured, sweatshirt-like silhouette even though it’s technically a T‑shirt. The tight ribs create a subtle puffiness and prevent the fabric from clinging to the skin, ensuring comfort in warmer months too. Additionally, its density makes it opaque (non-see-through), helps conceal sweat marks, and offers a sense of coverage and confidence.
The fit tends to be boxy and vintage-inspired, closely resembling a short-sleeved sweatshirt. Some models include classic design touches like double-V collar inserts and double stitching for durability and aesthetic appeal.
Made in Japan—specifically in Fukui prefecture—by Jackman, a brand known for combining heritage American sportswear inspiration with Japanese craftsmanship.
Fit Notes: This shirt follows Japanese sizing and runs slightly small. To maintain its intended boxy fit, we recommend choosing one size up from your usual American size. If you prefer a more standard or slimmer fit, you can also go true to size.
