GSM stands for grams per square metre — a simple way to measure how heavy and dense a fabric is. Here's what it means for how a t-shirt feels.
Lightweight
Thinner, cooler, and more breathable. Great for hot weather or layering.
Midweight
The everyday sweet spot. Substantial enough to hold its shape, soft enough for daily wear.
Heavyweight
Denser, more structured, and more durable. Feels premium and drapes well, at the cost of being warmer.
Lighter doesn't mean lower quality, and heavier doesn't always mean better — it depends on how and where you'll wear it.
