- A brand new 7.5oz Loop wheeled cotton jersey, designed and developed specially for this T-Shirt
- "Tokyo Shitamachi Body", which roughly translates to Tokyo Old Town Body; the cotton jersey is sourced from Wakayama and the dyeing and sewing done in old town Tokyo
- These shirts must be washed before wear, in so doing the fabric will "bed-in" and become thicker and more durable
- Raw, so come slightly oversized and will shrink to size (sizing table is post shrink size)
