Description
This Iron Heart ‘Spark Plug’ 7.5oz Loopwheeled Tee hits like a spark to the piston: loopwheeled, printed in Tokyo, and built to ride with you. At 7.5oz, it’s lighter than the brand’s denim tanks but still carries that unmistakable weight in feel and presence. The back graphic nods to their iconic 21oz and 25oz jeans, reimagined through the lens of classic motor mechanics.
The fabric is knit on classic “tsuriami-ki” machines – low-tension, circular-knit, no side seams. Cut, sewn, and printed in Tokyo’s historic Shitamachi neighborhood, every tee is a product of skilled hands and slow production.
It’s a mission statement – built for the road!
