What Is a Heavyweight Hoodie? GSM, Fit and What to Buy

A heavyweight hoodie is a hoodie cut from thick fleece, roughly 340–400+ GSM (grams per square meter), versus 180–280 GSM for lightweight ones. The weight is the point: it holds its shape, hangs straight instead of clinging, survives years of washing, and keeps you warm between sets without a jacket over it.

Most hoodies sold as "premium" are midweight at best. Here's how to tell the difference, how one should fit if you lift, and what to check before you pay for one.

What does GSM mean on a hoodie?

GSM is the weight of one square meter of the fabric, in grams. Higher GSM means denser, thicker cloth. It's the only number on a hoodie that tells you how heavy it really is, because "heavyweight" on a label is not regulated. Maker's Row defines GSM exactly that way and puts heavyweight hoodies at 350+ GSM.

Weight class	Typical GSM	What it feels like	Best for
Lightweight	180–280	Thin, drapes and clings	Layering, warm weather
Midweight	280–340	Standard retail hoodie	Everyday wear
Heavyweight	340–400+	Dense, structured, holds its shape	Cold gyms, the walk to the car, years of wear

Ranges vary by source by about 20 GSM. Melbourne Merch's fabric guide starts heavyweight at 340 and runs it to 400+.

Heavyweight vs regular hoodie: what's actually different?

A regular hoodie is usually 280–320 GSM; a heavyweight one is 340 and up. That extra weight changes four things you'll notice in the first week:

• Shape. Thick fleece stands off the body. It doesn't cling to a pump or show every fold of the tee under it.
• Warmth. Brushed fleece traps heat. A heavy one replaces a jacket for a cold garage gym or a 6 a.m. walk in.
• Durability. Denser knit pills less and keeps its hood and cuffs from going limp after a few washes.
• Weight on the body. You'll feel it. That's the trade: it's not a hoodie for a hot day.

Fleece vs French terry: which is heavier?

Fleece is brushed on the inside, fuzzy, and traps heat. French terry is looped and unbrushed, lighter and more breathable. Most true heavyweights are brushed or loopback fleece. If a "heavyweight" hoodie has a flat, looped inside and feels airy, it's probably terry at a lower weight. Terry isn't worse. It's a different job.

How should a hoodie fit if you lift?

The shoulder seam should sit at your shoulder point or just past it, sleeves should end at the wrist bone, and the hem should land at your belt line or slightly below. Lifters need room in the chest and lats so the hood doesn't pull back when you reach forward.

Check	Good fit	Too small
Shoulders	Seam at or past the shoulder point	Seam sits up on the deltoid
Chest / lats	Room to cross your arms without strain	Pulls across the back when you reach
Sleeves	End at the wrist bone, cuff holds	Ride up past the wrist on a press
Hem	At or just below the belt line	Rides up when you bend over

Want the oversized hang that matches a heavyweight oversized tee? Size up one. That's the call on our own hoodie too: order your normal hoodie size for a standard fit, one size up to hang loose.

Is a heavyweight hoodie worth it?

Yes, if you'll wear it more than one season. A heavy hoodie usually costs more up front, but the denser fabric keeps its shape and color through far more washes than a thin one, so the cost per wear drops. The same math applies to tees: see are heavyweight t-shirts worth it. If you only need something for an hour on a cool morning, a midweight does the job.

How do you wash a heavyweight hoodie so it lasts?

Wash cold, inside out, and tumble dry low or hang it. Never iron over the print. Heat is what shrinks cotton fleece and cracks graphics. It's the same reason graphic tee prints crack and peel. Turn it inside out and the face of the fleece and the print stay protected from the drum.

What to wear for this
