Quick answer: GSM (grams per square metre) is the weight of the fabric. For a hoodie, under 250 GSM is lightweight, 250 to 329 GSM is midweight, 330 to 449 GSM is heavyweight and 450 GSM and up is ultra-heavyweight. For most people a 400 GSM hoodie is the best everyday weight.
What is GSM, and why does it decide whether a hoodie is actually good?
GSM stands for grams per square metre, the weight of the fabric used to make a garment. It is the most honest number on a hoodie's spec sheet, because unlike words like "premium," "heavyweight" or "luxury," it can't be faked. It tells you exactly how much material you are getting.
Most fast-fashion hoodies sit somewhere between 180 and 280 GSM. They feel light in the hand, thin against the skin, and lose their shape within a few washes. A heavyweight hoodie starts at about 330 GSM and climbs from there. You feel the difference the moment you pick one up: weight, structure and a density that drapes instead of clinging.
If you only learn one thing about judging hoodie quality, learn to check the GSM. Everything else follows from it.
Hoodie GSM chart: what each weight feels like
| GSM | Weight class | What it feels like |
|---|---|---|
| 150–249 | Lightweight | Summer tees and the cheapest hoodies. Thin and breathable, fine for layering, no structure of its own. |
| 250–329 | Midweight | The standard mall-brand hoodie. Comfortable, but it drapes softly and thins out over time. |
| 330–449 | Heavyweight | Where real quality begins. Holds its shape, has presence and survives heavy rotation without sagging. The sweet spot for everyday premium streetwear. |
| 450+ | Ultra-heavyweight | Built like outerwear. Thick, structured and warm, with a density you feel the second you put it on. |

A 300 GSM tee is a heavy tee; most everyday t-shirts sit around 150 to 200 GSM. Each product page lists its exact weight and fabric.
Does higher GSM always mean better?
Not automatically, and this is where honesty matters more than marketing. A higher GSM means a heavier, warmer, more structured garment. That is exactly what you want in a hoodie built to last and to hold an oversized silhouette. But "best" depends on what you're after:
- If you want warmth, structure, durability and that substantial streetwear drape, higher GSM (400 to 500) is genuinely better.
- If you want something light for warm weather or for layering under a jacket, a midweight piece may suit you more.
Be suspicious of a brand charging premium prices while hiding the GSM. If a hoodie is genuinely heavyweight, the brand will tell you the number, because it's a selling point. Silence on GSM usually means the answer is "not much."
Is 350 GSM good for a hoodie?
Yes. 350 GSM is heavyweight: noticeably thicker and more structured than a typical 250 to 300 GSM hoodie, while staying comfortable for layering. Our Hot Pink hoodie is 350 GSM cotton-blend fleece.
Is 400 GSM good for a hoodie?
Yes. 400 GSM is the sweet spot most premium streetwear brands aim for. It gives real structure and warmth without feeling like armour: it holds an oversized drape, survives years of washing and still moves comfortably through daily wear. Our Angel Number and Signature hoodies are built at 400 GSM.
400 GSM vs 500 GSM: which should you buy?
Both are heavy. The choice comes down to climate and the drape you like.
- 400 GSM: the everyday heavyweight. Warm, structured and comfortable across seasons. If you want one hoodie for daily wear, layering and mild winters, this is the pick, like the 555 Angel Number Hoodie.
- 500 GSM: the statement ultra-heavyweight. Maximum structure and warmth for cold climates and the boldest oversized silhouette, like the Legends Heavyweight Hoodie in Olive Green.
Construction matters as much as the number: a well-cut 400 GSM hoodie will outlast a sloppy 500 GSM one every time.
GSM isn't the whole story: the other quality signals
Fabric weight is the foundation, but a great hoodie gets a few more things right. When you're judging quality, also look at:
- Composition: is it cotton, a cotton-rich blend or mostly polyester? Cotton and good cotton-poly blends feel and breathe better than synthetic-heavy fabric. Dope Beyond uses 100% cotton and cotton-blend fleece; each product page lists the exact fibre content.
- Construction: ribbed cuffs and hem that snap back into shape, reinforced stitching at stress points and a hood that holds its form. These are the details that separate a hoodie that lasts from one that warps.
- Fit and cut: heavy fabric only looks right if the cut is designed for it. Oversized, dropped-shoulder cuts show off the drape heavy fabric creates.
- Decoration: embroidery holds up best of all. A well-cured screen or puff print also lasts for years; cheap heat-transfer prints are the ones that crack and peel. Our Angel Number and Signature hoodies are embroidered, and the Legends Series uses puff print.
How to check GSM quality for yourself
You don't need a lab. Here's how to judge a hoodie in seconds, online or in hand:
- Online: look for the GSM figure in the product description. 330 or more means heavyweight. If it's missing, treat that as a red flag and ask.
- In hand: pick it up. A heavyweight hoodie has obvious heft. Hold the fabric to the light: denser fabric lets less light through. Scrunch it and let go; quality fabric springs back rather than staying crumpled.
- After a wash: the real test. A quality heavyweight piece keeps its shape, colour and density. A cheap one pills, thins and shrinks.
For the routine that keeps heavyweight fleece at its best, see how to wash a heavyweight hoodie without shrinking it.
Why Dope Beyond builds heavyweight
Dope Beyond was built on the belief that a hoodie should feel like something. Every hoodie, jogger and set we make is 340 to 500 GSM cotton or cotton-blend fleece, cut for an oversized streetwear fit and finished to survive years of rotation rather than a single season.
That's the point of the Lifestyle of Legends: gear that holds up, holds its shape and feels as good on its hundredth wear as its first. Browse the hoodie collection and check the GSM on every piece, or see our roundup of the best heavyweight hoodies from Canadian brands.
Frequently asked questions
What GSM is a good hoodie?
A durable, good-quality hoodie starts at about 330 GSM. Anything from 330 to 500 GSM is heavyweight to ultra-heavyweight and will have real structure, warmth and longevity. Below about 300 GSM you're in lightweight, fast-fashion territory.
Is a 340 GSM hoodie good?
Yes. 340 GSM is heavyweight. It has more structure and warmth than a typical 200 to 280 GSM fast-fashion hoodie while staying comfortable for layering. Our Jet Black and Beige Legends hoodies are 340 GSM.
Is 500 GSM too heavy for a hoodie?
Not at all. 500 GSM is ultra-heavyweight and built for structure, warmth and an oversized drape. It's ideal for colder weather and for anyone who wants a substantial statement piece. If you run warm or want something for layering, a 350 to 400 GSM piece may feel more comfortable.
What GSM do premium streetwear brands use?
Premium streetwear brands typically use 330 to 500 GSM for their heavyweight pieces. Below 300 GSM you're in fast-fashion territory regardless of the price tag.
Why don't some brands list their GSM?
Usually because the number isn't impressive. Brands that build genuinely heavyweight garments list the GSM because it's a selling point. When it's hidden, the fabric is often lightweight.
Does higher GSM mean a hoodie lasts longer?
Generally yes, with good construction. Heavier fabric resists thinning, pilling and losing shape, so a well-made heavyweight hoodie typically outlasts a lightweight one by years.
