How to Choose Hoodie Fabric: GSM, Blends and Finish

Why GSM Is the First Number to Look At

Ask any garment factory what makes a good hoodie and the conversation starts with one number: GSM, or grams per square meter. GSM measures fabric weight — how many grams a one-square-meter cut of the fabric weighs. A lightweight 240 GSM hoodie feels like a long-sleeve sweatshirt, while a 400 GSM heavyweight fleece feels structured, dense and premium. For brands, GSM is not a technicality; it is the single biggest driver of cost, warmth, drape and how customers perceive quality the moment they touch the garment.

Most brands settle into three weight classes. Lightweight fleece (240–280 GSM) works for layering pieces, spring drops and activation wear where breathability matters more than bulk. Midweight (300–340 GSM) is the industry sweet spot — warm enough for autumn, flexible enough for indoor wear, and the most common specification for private label programs. Heavyweight (350 GSM and up) targets the premium streetwear segment: stiff collars that hold shape, a substantial hand feel and minimal cling. If your brand promise is “premium basics”, starting at 350 GSM is usually the right call.

Cotton, CVC or Poly Blends: How the Mix Changes Everything

Once you have picked a weight, the fiber mix decides how the hoodie behaves over its life. Three constructions dominate custom production:

• 100% cotton fleece — the softest hand feel and the best surface for printing. The trade-offs are higher shrinkage (usually 3–5% if not pre-shrunk) and a heavier price tag when cotton markets move.
• CVC (chief value cotton, 60% cotton / 40% polyester) — the workhorse of private label hoodies. It keeps most of cotton’s comfort while the polyester share stabilizes the fabric, reduces shrinkage and improves color retention after repeated washing.
• Polyester-rich fleece — the most economical and the most colorfast, but it pills faster and feels less natural. It suits promotional runs and price-driven collections more than premium retail.

Our advice to brands ordering their first custom run is usually CVC at 320–330 GSM: it photographs well, survives the laundry test and keeps landed costs predictable.

Brushed, Unbrushed and the Finish That Decides Feel

Two fabrics with identical GSM can feel completely different because of finishing. Brushed fleece is sanded on the inside to create a soft, fluffy surface — this is the classic cozy hoodie interior customers love. Unbrushed fleece keeps a flatter interior, which prints more cleanly and sheds fewer micro-fibers. French terry, technically not fleece at all, uses looped yarns on the inside for a lighter, more breathable garment that works year-round.

Ask your supplier one specific question before approving a sample: is the fabric ring-spun and combed? Ring-spun yarns are smoother and stronger than open-end yarns at the same weight. Open-end fleece is cheaper — and it is the reason some samples feel rough after three washes.

Matching Fabric to Your Market

The right specification depends on where and how your customers wear the garment. For US streetwear brands, we typically recommend 350–400 GSM brushed CVC with a double-lined hood. For EU boutiques focused on layering, 280–300 GSM French terry performs better across seasons. For promotional and event merchandise, 240–280 GSM open-end poly fleece keeps budgets under control.

Another factor worth planning early: custom dyeing. Stock colors ship fast and cheap. Custom-dyed fleece usually adds fabric MOQ (often 300–500 kg per color) and two to three weeks of lead time. Brands that need brand-exact colors should budget for this from the start instead of discovering it mid-season.

Frequently Asked Questions

What GSM is considered premium for hoodies?

In most retail markets, 350 GSM and above reads as premium. Between 320 and 350 GSM you get a versatile mid-heavyweight that still appeals to mainstream buyers.

Will a heavier hoodie shrink more?

Not necessarily. Shrinkage depends on fiber content and finishing, not weight. Pre-shrunk CVC fleece typically holds within 3%, regardless of GSM.

Can I mix weights inside one collection?

Yes — many brands run a 400 GSM hero hoodie alongside 280 GSM layering pieces. The contrast actually strengthens the premium perception of the heavier piece.

The Factory-Side Bottom Line

Fabric choice is a business decision disguised as a technical one. Before you approve a sample, hold the fabric, wash it twice and check the seams.
