Cotton isn't just cotton — the weight of the fabric, measured in GSM (grams per square meter), changes everything about how a t-shirt looks, feels, and holds up over time. If you've ever bought a tee that felt papery-thin after one wash, GSM is usually the reason.
What GSM actually means
GSM measures the density of the fabric. A basic 140-160 GSM tee is light and breathable but often see-through and prone to losing shape fast. Mid-weight sits around 180-200 GSM — a common standard for everyday tees. Heavyweight, 220-240+ GSM, is thicker, more structured, and built to hold a specific silhouette — which is exactly why it's the standard for oversized and streetwear-style tees.
Why heavyweight cotton suits oversized fits specifically
An oversized cut relies on the fabric holding its drape without collapsing or clinging. Thin fabric on a loose cut just looks sloppy — it bunches, wrinkles, and loses the clean drop-shoulder line that makes the style work. Heavyweight cotton keeps its structure, so the tee hangs the way it's designed to, wash after wash.
Durability and print quality
Heavier fabric also holds prints better. DTG (direct-to-garment) and screen prints sit more securely on a denser weave, resist cracking, and fade slower than on thin fabric. If you're paying for a detailed graphic print, the GSM of the shirt underneath directly affects how long that print actually lasts.
How to check before you buy
Most product pages list GSM in the fabric details. As a rough rule: under 180 GSM is lightweight, 180-200 is standard, and 220+ is heavyweight. For oversized or graphic-heavy tees, aim for 220 GSM or above.
Every VASQ tee is printed on 240 GSM heavyweight cotton — you can see the full fabric specs on any product page.
