Built Like
A Tank

Most tees are featherweight. Ours is 400 grams of structured cotton that stands up on its own.

Cotton yarn ready for weaving heavyweight cloth
Weight you can actually feel

Pick up a normal t-shirt, then pick up this. You'll feel the difference before you've read a single spec. That difference has a number, and the number is 400.

400 grams per square metre. More than double a typical tee, the line between fabric that drapes and fabric that holds.

What 400gsm Actually Means

GSM is grams per square metre, the standard way to measure how heavy a fabric is. A typical t-shirt lands around 150–180gsm. At 400, this cotton is more than twice that: dense, structured, substantial in the hand.

That number isn't showing off. It's the difference between a shirt that clings and one that stands up on its own.

Where 400gsm Sits

Fabric weight in grams per square metre. Longer bar means heavier, denser cloth.

Typical industry weights. Most “heavyweight” tees stop around 220gsm. We kept going.

Why We Make It This Heavy

Most brands trim the weight to trim the cost. We went the other way. This is cotton with real presence, structured enough to hold its shape, substantial enough that it feels like an investment the moment you put it on. And somehow it's still soft, buttery almost, against the skin. Heavy and soft aren't supposed to go together, but here we are.

Right now it only comes one way: a classic boxy tee, cut generous through the body. No spinoffs, no variations, just the one piece done properly. Wear it under something when it's cold, wear it alone when it's not, wear it every day if that's the plan. It's built for exactly that.

No Sugarcoating

What It's Actually Good At

Scored out of five. Buy it once, wear it for years, that's the pitch.

An Investment You Wear

The dense weave holds up over years of wear and washing, this is the piece you keep, not the one you replace. Wash it cool, hang to dry, let it settle in. Cut and sewn by hand in Ecuador, finished with tagua nut buttons.
