How to Choose Your Size in Oversized and Boxy Fit Clothing

When comparing hoodies, almost everyone looks at a single number: the weight. The higher the GSM, the more premium the garment seems. But that assumption is incomplete — and in some cases, flat out wrong.

In this guide we break down what GSM actually is, why a high number doesn't guarantee quality, and what to look at instead before deciding if a hoodie is worth your money.

What GSM actually is and what it measures

GSM stands for "grams per square meter" — basically, how much the fabric weighs across a given area. A GSM of 180 is a lightweight cotton, the kind used in basic summer t-shirts. A GSM of 400 is a dense, heavy fabric, typical of premium winter hoodies.

So far, it all checks out: more grams per square meter usually means a thicker fabric with more body. The problem shows up when we assume weight automatically means quality.

Why a high GSM doesn't guarantee quality

GSM only measures density, not what the yarn is made of or how it's constructed. You can get a 400 GSM fabric using low-quality cotton, poorly spun, just by packing more fiber into the weave. The result is a hoodie that's heavy on the hanger — but stiff, that doesn't drape well, and that loses its shape at the collar and cuffs after a few washes.

A high GSM with poor fiber gives you a hoodie that weighs a lot but performs badly once you actually wear it. A more moderate GSM with good cotton and good spinning can drape better, feel better, and last a lot longer.

So when does GSM actually matter?

This doesn't mean GSM is irrelevant — quite the opposite. For hoodies and oversized garments, a weight between 340 and 400 GSM is still the sweet spot for the drape and structure that premium streetwear is going for. The key is that a high GSM needs quality fiber and spinning behind it to actually deliver.

When a high GSM is paired with quality cotton, that's when you really feel the difference: the garment has real weight in hand, drapes with structure on the body, and holds up wash after wash without losing its shape. Weight is one piece of the puzzle — not the whole puzzle.

The factors that actually determine hoodie quality

The type of fiber. Combed cotton removes short fibers and impurities before spinning, giving you a stronger, softer-feeling yarn. Uncombed carded cotton is cheaper to produce but pills a lot faster.

The type of yarn. Compact yarn has less surface fuzz than a regular spun yarn, which means a smoother surface that's less likely to pill with use.

The finish. The interior brushing is what determines the real hand-feel and warmth of a hoodie, beyond the GSM number. A good finish can make a moderate GSM feel more premium than a high one that's poorly brushed.

The seams and construction. Double stitching in stress zones (shoulders, armholes, hems) and reinforced collars and cuffs are quality signals that have nothing to do with fabric weight, but that determine how long the garment actually lasts.

How to tell if a hoodie is quality without relying on GSM alone

Before deciding based on the weight number alone, try this:

Touch the inside. Good brushing feels soft and dense, not rough or with loose fuzz coming off.

Check the seams. They should be straight, double-stitched in stress zones, with no loose threads anywhere.

Stretch the fabric a little. It should bounce back without staying warped or turning see-through in the stretched spot.

Check the weight in hand, not just the spec sheet. A high GSM with poor fiber sometimes feels lighter than the number promises — that's a sign something's off.

At GODS® we combine weight and fiber quality

At GODS® we work with heavyweight cotton between 340 and 400 GSM, but the weight is only the starting point. We pick quality fiber and take care of the finish on every garment so fabric weight actually translates into real drape, durability, and hand-feel — not just a number on the label.

Next time you're comparing hoodies, don't stop at the GSM. It's a useful data point, but it only tells part of the story.
