Cotton vs Fleece vs French Terry: Which Hoodie Fabric Fits Your Climate

You bought a hoodie in October that felt perfect in the fitting room, and by January you're wearing a jacket over it just to walk the dog. Sound familiar? The problem usually isn't the fit or the brand — it's that nobody explained the differences between hoodie fabric types before you handed over your card. Cotton jersey, fleece, and French terry all look nearly identical folded on a shelf, and they behave completely differently once the temperature moves.

Here's what we'll cover: how each of the three main fabrics actually performs, which climates they suit, and how to read a product page so you can tell what you're buying before it arrives. Get this right once and you'll stop buying hoodies that only work six weeks a year.

Why GSM Matters More Than the Fabric Name

Before comparing hoodie fabric types, understand the number that sits underneath all of them: GSM, or grams per square metre. It's the weight of the fabric, and it tells you more about warmth than any marketing copy will.

Lightweight hoodies land around 240–280 GSM. Midweight sits between 300 and 380. Anything above 400 GSM is genuinely heavy — the kind of piece that holds its shape on a hanger and takes a full day to air dry.

A 280 GSM fleece and a 420 GSM French terry are not remotely comparable garments, even though both are technically "fleece-family" fabrics. Always check the weight first, then the fabric type.

Cotton Jersey: The Year-Round Layer

Cotton jersey is the same knit structure as a good t-shirt, just heavier. Smooth on both faces, no loops, no brushing. It breathes better than anything else on this list.

This is your fabric if you live somewhere warm or humid — coastal cities, southern states, anywhere the evening drop is ten degrees rather than thirty. It's also the best choice if you're a commuter who moves between an air-conditioned office and a hot street twice a day.

The trade-off is real, though. Jersey has almost no insulating air pockets, so once the wind picks up, you'll feel it. Don't buy jersey expecting winter performance.

Fleece: Built for Cold, Not for Longevity

Fleece is a knit fabric with the interior surface brushed to raise a soft, fuzzy nap. Those raised fibres trap warm air against your skin, which is why fleece feels warmer the second you put it on.

Where fleece wins

Cold, dry climates. If you're in the Midwest in February or anywhere that regularly drops below freezing, brushed fleece is doing the most work per gram.

Where fleece disappoints

Those brushed fibres flatten. After thirty or forty washes, a cheap fleece loses loft, pills at the cuffs and underarms, and starts to look tired. Quality matters enormously here — ring-spun cotton fleece with a high cotton content holds up far better than a poly-heavy blend.

We've had customers come back specifically because the fleece hoodie they'd worn for two seasons still looked like the one they'd unboxed. That's a construction and fibre decision, not luck.

French Terry: The Fabric Most People Should Be Buying

French terry sits between the other two. The outer face is smooth like jersey; the inner face has soft, unbrushed loops. Those loops create structure and a little insulation without sealing in heat.

That combination makes French terry the most versatile of the hoodie fabric types available in 2026, and it's why so many premium labels have shifted their core programmes toward it. It drapes better, it doesn't pill the way brushed fleece does, and it absorbs moisture instead of trapping it against your skin.

• Transitional seasons: spring and autumn, where a fleece is too much and jersey isn't enough
• Mild winters: anywhere the low sits in the 40s and 50s
• Active wear: gym sessions, morning runs, anything where you'll warm up mid-wear
• Layering: the flat outer face slips under a jacket without bulk

If you own one hoodie, make it heavyweight French terry. If you want the decision made for you, REDBYWM's Premium Hoodies and Tee's are built on midweight-to-heavy terry precisely because it works across the widest range of conditions.

Matching Fabric to Your Actual Climate

Be honest about how you live, not how you'd like to. Someone in Phoenix who spends nine months in air conditioning has closer needs to someone in Seattle than the outdoor temperature suggests.

Quick guide: consistently hot and humid, go jersey. Sub-freezing winters, go brushed fleece at 400 GSM or above. Everything in between — which is most of us — go French terry.

Reading a Product Page Like a Buyer, Not a Browser

Three things tell you almost everything. Look for the GSM figure, the fibre composition, and the words "brushed" or "loopback." If a brand won't publish the weight, that's usually because it isn't flattering.

Also check the cotton spinning method. Ring-spun or combed ring-spun cotton produces a smoother, stronger yarn that resists pilling — worth paying for if you plan to keep the piece more than a season.

Understanding hoodie fabric types turns a guessing game into a straightforward decision, and it saves you from that annual cycle of buying something that's wrong by the time you need it most. Start with your climate, confirm the GSM, then check the fibre quality. Buy fewer hoodies and buy heavier ones — a well-constructed French terry piece will outlast three cheap fleeces and look better doing it. When you're ready to put that into practice, browse the hoodie range at REDBYWM and check the fabric specs against your own weather before you decide.
