Short answer: a 400 GSM hoodie is cut from fabric that weighs at least 400 grams per square metre. That is heavyweight: thicker, warmer and more structured than a typical 280–330 gsm hoodie. You do not need to spend $120+ to get one — all eight picks below are 400–500 gsm and cost $49–$69 (US prices at the time of writing).
What 400 GSM actually changes
Fabric weight is the single best predictor of how a hoodie looks after a year. At 400 gsm and above the hood stands up instead of collapsing, the body keeps a square, boxy line, and the fabric does not cling to your shoulders. The trade-off is warmth and weight: a 480 gsm hoodie is a cold-weather piece, while 400–420 gsm works from autumn to spring.

What to check besides the number
- Fibre: 100% cotton or a cotton-rich blend breathes better than polyester-heavy fleece of the same weight.
- Finish: brushed fleece inside feels warmer; loopback or plain cotton feels drier and more structured.
- Washing after sewing: washed, sunfade and vintage-wash pieces are pre-washed, so they shrink less at home.
- Measurements: heavyweight hoodies are usually cut boxy. Compare chest width and length with a hoodie you own — see how to choose an oversized hoodie size.

FAQ
Is 400 GSM a good weight for a hoodie?
Yes. 400 gsm is where a hoodie starts to feel properly heavyweight: structured, warm and durable, without being as stiff as 500 gsm.
Is 400 GSM too hot to wear?
Not if it is mostly cotton. It suits autumn to spring on its own and layers under a coat in winter.
What is the difference between 400 and 480 GSM?
480 gsm is about 20% denser: stiffer, warmer and more boxy. 400–420 gsm drapes a little more and is easier to wear across seasons.
Do heavyweight hoodies shrink?
Pre-washed pieces (washed, sunfade, vintage wash) shrink very little. For the rest, wash cold and air-dry.
