Premium streetwear is built on feel. When customers pick up a tee or hoodie, they notice weight before they notice anything else. That weight is measured in GSM, grams per square meter, and choosing it is one of the most important decisions in your tech pack.
What GSM tells you (and what it does not)
GSM measures how much a square meter of fabric weighs. A higher number means denser, heavier fabric. It does not describe quality on its own. Two fabrics with the same GSM can feel very different depending on fiber, yarn, and knit.
Typical GSM ranges
These are general industry ranges, and exact classifications vary by brand and market.
| Garment | Lightweight | Midweight | Heavyweight |
|---|---|---|---|
| T-shirts | 120–180 GSM | 180–220 GSM | 220–300 GSM |
| Hoodies and sweatshirts | 200–280 GSM | 280–380 GSM | 380–500+ GSM |
Premium oversized tees commonly sit in the 220–270 GSM range, while heavyweight hoodies often run from about 400 to 500 GSM.
How weight changes the garment
Drape and shape. Heavier fabric holds structure, which is why boxy and oversized silhouettes use it. Lighter fabric drapes closer to the body.
Feel and perceived quality. Heavier weights read as premium to many customers, but too heavy can feel stiff.
Season. Lighter weights suit warm weather. Heavyweight fleece suits cold-weather collections.
Cost. More GSM means more material per garment, which raises fabric cost, and sometimes shipping weight as well.
Fiber and finish matter as much as weight
Combed cotton is smoother and more refined than standard cotton, and is commonly chosen for premium tees.
Brushed fleece has a soft inside surface; the finish affects warmth and feel.
Cotton and polyester blends (for example 80/20) can improve shape retention and reduce shrinkage compared with 100% cotton.
Pre-washing and shrinkage control affect how the garment fits after your customer washes it.
How to choose
Define the silhouette. Oversized and boxy styles benefit from heavier fabric.
Match the season and market. A heavyweight hoodie suits fall and winter collections.
Balance feel and price. Request swatches or reference garments to compare options in your hands.
Write it in the tech pack. State fabric composition, GSM, knit type, and finish, so your samples match what you picture.
