What GSM means
GSM (grams per square metre) is the weight of one square metre of fabric. It's the simplest way to compare fabric density across suppliers.
Hoodie weights at a glance
| Category | Approx. GSM | Feel and use |
|---|---|---|
| Lightweight | Under 280 | Layering, warm climates, cheaper promo hoodies |
| Midweight | 280–350 | Everyday retail hoodies, most mass-market brands |
| Heavyweight | 350–450 | Premium streetwear; structured drape |
| Super heavyweight | 450+ | Statement pieces; very dense, boxy shape |
These ranges are common industry shorthand rather than strict standards — always compare actual samples.
Fleece vs French terry
- Brushed fleece — the inside loops are brushed into a soft, fluffy surface. Warmer, cozier, can pill if low quality.
- Loopback French terry — the inside loops are left unbrushed. Cleaner look, breathes better, popular for washed and vintage styles.
The same GSM can feel very different in each, so specify both weight and construction.
Beyond GSM: what makes a hoodie premium
- Yarn quality — combed, longer-fiber cotton feels smoother and pills less.
- Knit density — a tight knit holds shape and prints better.
- Shrinkage control — pre-shrunk fabric and garment washing.
- Rib quality — cuffs and hem that spring back.
- Hood construction — double-layered, with a hood that stands up.
- Fit — heavyweight fabric needs a pattern built for it, usually boxier with a dropped shoulder.
Choosing your weight
- Launching a premium streetwear brand? Start around 400 GSM.
- Making merch or promo hoodies? 300–350 GSM keeps cost down.
- Selling in hot climates? A midweight French terry may sell better than heavy fleece.
- Building a hero piece? Go 450+ with a washed finish.
Tip: order samples in two weights and wear-test them. Customers feel the difference instantly.
