Which GSM is right for a sweatshirt, T-shirt, or trousers?

There's no single right number — it depends on how the garment is meant to sit. A sweatshirt generally wants 280 GSM or higher to hold its shape and feel substantial. A T-shirt reads as heavyweight anywhere above 200–250 GSM; most retail tees sit closer to 150. Trousers vary widely by fabric — terry and fleece trousers commonly run 250–350 GSM.

Our own answer, by piece:

Sweatshirt — The Quiet Sweatshirt is 282 GSM, cotton-spandex jersey. Heavy enough to feel grounding rather than bulky; if a lighter layer is what you want, this isn’t that piece — say so plainly, per our own register, rather than oversell it.

T-shirt — The Everyday Tee is 270 GSM, roughly double a standard tee’s weight, stone-washed so the density doesn’t read as stiff.

Trousers — two pairs, one shared cut, different cloth: The Easy Trouser in 340 GSM cotton terry (denser, firmer hand) and The Weekend Trouser in 270 GSM brushed cotton fleece (lighter, softer). Same fit either way — the fabric is the only real choice between them, so choose by hand, not by guessing at a number.

Caftan (outside the three-category cluster, included because it’s our lightest piece and the honest counterpoint to “heavier is better”) — The Long Quiet at 136 GSM, jute-cotton, made to move rather than hold a shape.
