Wonder Looper Double Heavyweight T-Shirt in Charcoal
A 409gsm Japanese jersey at roughly twice the weight of a standard heavyweight tee
Specimen · 2026-10-16 iron · K73
A T-shirt is usually the lightest thing in a wardrobe. This one is cut from 409-gram jersey, close to double the weight of a conventional heavyweight, in a charcoal dense enough to read as slate.
The cloth is all cotton, circular knit in Japan, with an uneven surface that shows as a faint heather up close. A ribbed binder collar holds the neckline flat, and the side seams are sewn flat on a Union Special machine. The fit is modern and athletic rather than boxy.
Wonder Looper makes the shirt in Japan and sells it through its own shop.
