How to Choose a 400 GSM Hoodie: Weight, Fit and Quality Explained

A 400 GSM hoodie can be an excellent choice when you want a substantial fabric feel and a more structured streetwear silhouette. But the number alone should not make the decision. Here is how to evaluate a 400 GSM hoodie before you buy.

What does 400 GSM actually mean?

GSM stands for grams per square metre. A 400 GSM fabric weighs 400 grams for every square metre of fabric. It does not mean the entire finished hoodie weighs 400 grams: garment size, panels, hood, pockets and trims all affect total weight.

Is 400 GSM good for winter?

It can be useful for cool-weather dressing, particularly when layered. Warmth also depends on fabric composition, whether the inside is brushed, the garment's fit and the weather. A heavy fabric is not automatically windproof or waterproof.

How should it fit?

Choose a regular cut for clean everyday styling, an oversized cut for drape, or a boxy cut for a wider and often shorter silhouette. Review actual garment measurements and decide whether you plan to wear a tee or additional layer underneath.

Check more than the GSM

Inspect cuff and hem construction, seams, hood shape, fabric care guidance and product photography. A well-presented listing should explain what you are buying rather than relying on generic luxury claims.
