7.1 oz super heavy-weight cotton.

An extra-thick, American-style body.

The appeal lies in the fabric thickness and the distinctive rough texture of open-end (air-spun) yarn.
This T-shirt delivers on the expectations of those who love tough heavyweight gear. Enjoy the character it develops the more you wear it.

In spring and summer, riders often get by with just a T-shirt, but night riding gets cold.
(For every 10 km/h increase in speed, the felt temperature drops by 1°C.)
Super heavy-weight cotton helps prevent your body temperature from dropping.

As an outer layer in spring/summer, and as an inner layer in fall/winter.
An unbeatable super heavy-ounce T-shirt.



We paid close attention to the pocket size and placement, and pursued optimal specs that make the most of this thick fabric feel.



An exceptionally embroidered patch, made entirely in Japan.



SPEED ADDICT’s trademark character, “Spearadi-kun.”
A Showa-retro design that brings back the good old days.

*Please refrain from the following:
Using a tumble dryer / ironing directly on the patch
