Built Like
A Tank
Most tees are featherweight. Ours is 400 grams of structured, stands-on-its-own cotton.

Pick up a normal t-shirt, then pick up this. You’ll feel the difference before you read a single spec. That difference has a number — and the number is 400.
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, and 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 = 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. It layers like outerwear and wears on its own all summer.
How It Actually Performs
Our honest take, scored out of five. Buy it once, wear it for years.
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, and let it settle in. Cut and sewn by hand in Ecuador, finished with tagua nut buttons.
