A good tee is not the one that looks new forever. It's the one that looks better old.
That's why we print on heavyweight ring-spun cotton and garment-dye every run. The first wash relaxes it. The tenth softens it. The fiftieth makes it unmistakably yours — the collar sits the way you wear it, the print carries a little of everywhere you've been.
Fast fashion is built to be replaced. We'd rather build something you keep — the shirt you reach for on the plane, the one your kid steals someday.
Care for it simply: cold wash, inside out, hang it when you can. Then just wear it. The aging is the point.
