When people talk about hoodie quality, they often mention GSM. Many buyers wonder if a 400GSM hoodie is considered good or if they need something heavier. GSM (grams per square meter) tells you how thick and dense the fabric is.
Yes, a 400GSM hoodie is considered very good quality. It is classified as a heavyweight hoodie. At this weight, the fabric is thick, warm, durable, and structured. 400GSM is often used for premium streetwear and high-quality custom hoodies.
I still remember the first 400GSM hoodie I made for a client. The fabric felt strong and soft, and the finished piece had a perfect drape. The client said it was the best hoodie they ever touched.

What does 400GSM mean for hoodies?
GSM measures the weight of the fabric. A higher GSM means a thicker, denser fabric.
A 400GSM hoodie uses fabric that weighs 400 grams per square meter. It is heavier and warmer than mid-weight hoodies (280–350 GSM) and falls into the premium heavyweight category.
Hoodie weight categories
| Hoodie Type | GSM Range |
|---|---|
| Lightweight hoodie | 200–280 GSM |
| Mid-weight hoodie | 280–350 GSM |
| Heavyweight hoodie | 400–500 GSM |

A 400GSM hoodie has more fabric density. This makes it warmer, less likely to stretch out, and more durable.
Is a 400GSM hoodie too heavy?
For most people, 400GSM is ideal for colder seasons.
A 400GSM hoodie feels thick and substantial but is still wearable. It is heavier than standard hoodies, making it great for autumn, winter, and cool spring weather.
When to choose 400GSM
- For streetwear brands that want a structured, luxury feel
- For customers who want a hoodie that lasts for years
- For layering in cold climates
Examples can be seen at Nike Club Fleece or Adidas Premium Hoodies.
How does a 400GSM hoodie compare to 500GSM?
500GSM is even heavier, but 400GSM is more versatile.
400GSM hoodies balance warmth and comfort. 500GSM hoodies feel like a coat and are used for very premium collections or very cold weather.
I’ve produced 500GSM hoodies before. They are very warm and structured, but some customers feel them too thick for daily wear. 400GSM is usually the sweet spot.
Does a 400GSM hoodie always mean high quality?
Weight alone does not guarantee quality.
A 400GSM hoodie is only as good as the fabric and construction. If poor cotton or cheap stitching is used, even a heavy hoodie can feel stiff or uncomfortable.
What else to check
- Fabric composition (100% cotton or premium blends)
- Stitching and finishing quality
- Fit and sizing accuracy
- Pre-shrinking and washing performance

Conclusion
A 400GSM hoodie is a heavyweight, premium-quality garment. It is warm, durable, and ideal for high-end streetwear or custom projects, as long as it is made with good materials and construction.
