Jersey fabric is the single most-produced knit in the world, sitting behind roughly 35% of all knit fabric output across European mills in 2025 (EURATEX, 2025). It is the fabric of the modern t-shirt, the base layer, the sweatshirt lining, and half the dresses in any given womenswear collection. If you're launching a clothing brand, jersey is the first fabric you'll quote, and probably the first you'll get wrong.

This guide covers what jersey fabric actually is, where it came from, how single jersey differs from interlock and rib, the GSM tiers used across Portuguese production in 2026, real EUR pricing per meter, MOQ patterns, and how our factory group produces it. Everything below reflects the manufacturer-side view, based on production runs coordinated across the Porto, Guimarães, Braga, Barcelos, and Famalicão regions.

What Is Jersey Fabric?

Jersey fabric is a weft-knit textile made on circular knitting machines, characterised by a smooth flat face on the outside and a slightly looped, ribbed back on the inside. It's the foundation of the modern t-shirt, and in Europe it accounts for roughly 35% of all knit fabric produced across textile mills (EURATEX, 2025).

The defining feature of jersey is its single-set-of-needles construction. One yarn loops through itself in continuous rows, creating a fabric that stretches sideways more than lengthways, drapes softly, and holds shape when finished properly. Unlike woven fabrics, jersey has natural give without any elastane, which is why it dominates casual apparel.

Within the knit-fabric family, jersey sits at the lightweight end. It's lighter than French terry, less dense than interlock, and structurally simpler than rib. That simplicity is exactly why it's the workhorse fabric of contemporary fashion. Nearly every garment factory can produce it, and every knit mill in the Ave Valley stocks it.

Other names you might see

Jersey shows up under several labels in supplier catalogues. "Single jersey" (the most common construction) is often shortened to just "jersey". "Plain knit" and "stockinette" refer to the same structure in knitting terminology. Portuguese mills usually call it "malha jersey" or "malha simples" in factory documentation. Whatever the label, the core structure is identical: one bed of needles, a single yarn feed, a flat face, and a ribbed back.

What Is the History of Jersey Knit?

Jersey fabric takes its name from Jersey, the largest of the Channel Islands off the coast of Normandy, where fishermen were wearing knitted wool garments called "jerseys" as early as the 1600s. What began as a warm, stretchy work garment for cold Atlantic labour eventually became one of the most disruptive fabrics in fashion history.

For centuries, jersey stayed in its lane as an underwear and workwear knit. Then in 1916, Coco Chanel used jersey knit, a fabric almost no couture designer had touched, to build a collection of relaxed, comfortable womenswear. The move was radical. Jersey had been considered a men's underwear fabric. Chanel's decision to build daywear from it is widely credited with opening modern comfort-first fashion.

By the 1930s, jersey was standard for sportswear. Post-war, it became the fabric of the American t-shirt. Today, according to Textile Exchange, cotton jersey remains the single most consumed knit construction globally (Textile Exchange, 2024).

Why the origin matters commercially: we've noticed that Portuguese mills lean into the "heritage knit" positioning when quoting European brands. It's not marketing fluff. The Channel Islands, coastal Portugal, and coastal France all sit in the same historic knitwear corridor, and Portuguese mills have been producing jersey continuously since the 19th century. That century-plus of local know-how is one reason Portuguese jersey consistently outperforms cheaper imports on hand-feel and dimensional stability.

Single Jersey vs Interlock vs Rib: What's the Difference?

The three most common jersey constructions differ in how many needle beds are used and how the loops interlock. Single jersey (one needle bed) is the lightest and most common. Interlock (two beds, interlocking loops) is denser and reversible. Rib (alternating knit and purl) has vertical stretch and structure. Together they cover roughly 78% of all knit apparel fabric produced in Europe (EURATEX, 2025).

Choosing between them is a first-order fabric decision. A t-shirt in interlock feels heavy and boxy. A polo collar in single jersey collapses. A bodysuit in rib fits like a second skin, but the same rib in a boxy tee reads underwear.

Single jersey

Single jersey is the default "jersey" people mean when they say "jersey". It's produced on one needle bed, giving a smooth outer face and a fine ribbed inner face. The fabric curls at raw edges because of the asymmetric construction, which is why every sewn t-shirt has hemmed edges. It's the lightest and most versatile of the three.

Interlock

Interlock uses two interlocking sets of needles that produce identical faces on both sides. The result is denser, more stable, and doesn't curl. Interlock is heavier than single jersey at the same yarn count and holds shape better through washing. Common in polo shirts, structured womenswear tops, kidswear, and premium base layers.

Rib

Rib knit alternates knit and purl stitches to produce visible vertical ribs. It stretches heavily across the fabric and contracts in the length. The most common variants are 1x1 rib (one knit, one purl, alternating) and 2x2 rib (two of each). Rib is what makes a collar hug, a cuff snap back, and a waistband stay put. On its own it makes bodysuits, tank tops, and slim-fit tees.

What Are the GSM Ranges for Jersey Fabric?

Jersey fabric is sold across a GSM (grams per square meter) range from around 120 GSM for the lightest women's tops up to 220 GSM for premium heavyweight tees. The 160 to 180 GSM band represents roughly 60% of European t-shirt production in 2025 (EURATEX, 2025), and is what most brands mean when they say "standard cotton tee".

Getting GSM right is often the difference between a tee that photographs premium and one that photographs cheap. This is a decision most first-time founders underweight.

Light jersey (120-150 GSM)

Light single jersey is used for sheer tops, dress linings, camisoles, kidswear, and lightweight base layers. Anything below 140 GSM will show what's underneath, so it's rarely used for standalone tees in most Western markets. Portuguese mills stock this weight primarily for women's tops and undergarment programmes.

Standard tee weight (150-180 GSM)

This is the default t-shirt weight, and by volume the most produced tier in Portugal. 160 GSM is the classic "standard cotton tee" that most emerging brands quote at their first sample stage. It works across seasons, prints well, and washes without excessive shrinkage when finished correctly.

Premium heavyweight (190-220 GSM)

This is where the "heavyweight tee" positioning lives. The fabric feels substantial, drapes with more structure, and reads premium on the shelf. Streetwear brands aiming for a boxy silhouette or a garment-dyed programme almost always land here. The trade-off: more yarn, higher price per meter, and slightly longer knit time.

Ultra-heavy jersey (220-260+ GSM)

Above 220 GSM, single jersey starts to compete structurally with light French terry. This tier is used for boxy premium tees, oversized silhouettes with body, and heavyweight base layers. Not every Portuguese mill stocks this weight in single jersey, because most brands looking for that weight move to French terry instead.

What Fibres Are Used in Jersey Fabric?

Cotton dominates jersey production globally, but in 2026 the composition mix is more diverse than it's ever been. Roughly 82% of European jersey production still uses cotton as the primary fibre, with the remainder split across viscose, Tencel, modal, and blends (Textile Exchange, 2024). Composition affects cost, drape, dye behaviour, and the whole hand-feel of the finished garment.

Choosing the right fibre is a positioning decision, not just a spec-sheet detail. A 160 GSM organic cotton jersey and a 160 GSM Tencel-cotton blend feel materially different on the body, and retailer buyers can tell the difference at first touch.

Combed cotton (the baseline)

Standard combed cotton is the workhorse fibre for jersey and covers the majority of Portuguese production. Combed cotton removes short fibres from the yarn before spinning, producing a smoother, stronger, more pill-resistant fabric than carded. Nearly every documented factory in our group produces jersey in combed cotton. Prices sit at the €3.50-7 per meter range across GSM tiers.

Cotton-elastane (95/5 or 92/8)

Adding 5-8% elastane to a cotton jersey produces a stretch fabric that keeps its shape through wear and returns to original dimensions after washing. This is the standard construction for fitted tees, women's basics, and any garment that needs cling without seams. Prices run €5-8.50/m at 200 GSM.

GOTS-certified organic cotton

Organic cotton jersey certified to the Global Organic Textile Standard is now offered by roughly 55% of documented Portuguese knit mills. It runs a 40-70% premium over conventional. Lead time is longer, typically 2-3 weeks more than conventional, because certified yarn has to be booked in advance. Prices sit at €6-10/m for 160-200 GSM.

Tencel and modal blends

Tencel (lyocell) and modal add drape and colour depth to a jersey blend. A 60/40 Tencel-cotton jersey drapes more like silk than cotton, holds dye colour better than pure cotton, and feels cool against the skin. The trade-off is cost: Tencel-cotton jersey blends run €9-14/m at 180-200 GSM. Modal-cotton sits in a similar range.

Composition patterns we've observed: across 2024-2026 production runs coordinated through our factory group, roughly 62% of jersey orders were standard cotton (conventional or organic), 24% included elastane for stretch, and 14% were premium blends (Tencel, modal, viscose). Emerging brands almost always start with cotton or cotton-elastane. Blend fabrics tend to come in from year two, when brands can absorb the cost premium.

What Garments Are Made with Jersey?

Jersey is the fabric behind the majority of casual apparel produced in Europe. T-shirts alone account for roughly 41% of all jersey fabric consumption in the EU in 2025, followed by dresses, base layers, and lightweight sweatshirt linings (EURATEX, 2025). It's genuinely difficult to open a wardrobe today without seeing multiple jersey garments.

Specific garment applications by GSM tier:

• 120-140 GSM (ultra-light): sheer tops, dress linings, camisoles, lightweight kidswear
• 150-170 GSM (light): fitted tees, summer dresses, women's basics, base layers
• 160-180 GSM (standard): everyday t-shirts, longline tees, polo bodies, casual dresses
• 190-220 GSM (heavy): premium tees, boxy silhouettes, oversized tees, garment-dyed programmes
• 220-260 GSM (ultra-heavy): boxy heavyweight tees, structured base layers

Beyond t-shirts, jersey shows up in dresses (particularly the 160-180 GSM band for daywear and 130-150 GSM for slip dresses), leggings and joggers (usually with elastane), tank tops in rib, polo shirt bodies (often single jersey with rib collar), and as a lining for structured outerwear.

What Does Jersey Fabric Cost per Meter in Portugal?

Jersey fabric prices at Portuguese mills in 2026 range from €3.50 per meter for standard cotton at 160 GSM to €14 per meter for premium Tencel-cotton blends. Composition, GSM, and certification are the three largest cost drivers, together explaining roughly 80% of price variance across Portuguese suppliers (ATP, 2025).

Founders benefit from understanding these tiers early. Fabric is typically 30-40% of the total garment cost on a jersey tee, so a €2/m difference in fabric moves the ex-factory garment price by €0.80-1.20 per unit.

Composition drives the base cost

Standard combed cotton jersey sits at the floor. Cotton-elastane blends run 20-30% higher, mostly because of the elastane cost and slightly more complex knitting. GOTS-certified organic cotton adds a 40-70% premium. Tencel and modal blends can run 2x the standard rate at the premium end.

GSM adds cost roughly proportionally

Doubling GSM roughly doubles yarn consumption. A 220 GSM heavy jersey uses about 40% more yarn than a 160 GSM standard tee weight, which typically increases fabric price by 30-50%. Machine time also increases, though less steeply.

Certifications add a measurable premium

OEKO-TEX Standard 100 alone (baseline safety certification) adds €0.30-0.80/m. Nearly all Portuguese knit mills carry this. GOTS adds €1-3/m over the same non-certified fabric. GRS (recycled content) adds €0.50-1.50/m. Stacked certifications compound.

Practical planning: for a standard tee using 1.2 meters of 160 GSM cotton jersey, a standard cotton fabric costs €4.20-6.60 per garment. Organic-certified fabric for the same tee costs €7.20-12. That fabric-only difference is often the first "sticker shock" moment for founders during their first quote.

What Are the MOQs for Jersey Production?

Minimum order quantities for jersey production in Portugal typically start at 100 units per style at documented factories in our group. Roughly 60% of factories accept 100-unit orders on standard cotton jersey without a major surcharge. Around 42% work most comfortably in the 100-300 unit tier (ATP, 2025).

Jersey has friendlier MOQs than most knit fabrics because so many Portuguese mills stock it in standard colours off-shelf. When the fabric doesn't have to be custom-knit for the run, the MOQ constraint often disappears entirely.

Small-batch (50-100 units per style)

Roughly 18% of documented factories in our group accept sub-100 orders on stock-dyed single jersey. These runs come with three trade-offs: a per-unit price surcharge (typically 15-25% above the 300-unit rate), longer sampling queues, and limited fabric colour options (stock only, no custom dye lots). Useful for testing a first collection or capsule drop.

Standard tier (100-300 units per style)

Around 42% of documented factories operate comfortably at 100-300 units per style. This matches the size of most emerging D2C and streetwear launches. Standard rates apply. Custom-dyed fabric colours are available above 200-250 units at most factories.

Mid-tier (300-1,000 units per style)

40% of documented factories operate here. CMT pricing is at its most competitive. Custom-dyed jersey becomes standard, and sample rounds compress to 1-2 iterations for clean tech packs. Most established brands scaling from launch to wholesale target this tier.

Sample-round patterns: across production runs coordinated through our factory group in 2024-2026, the typical sample count for a clean tech pack on plain single jersey was 1-2 rounds. On complex constructions (rib collars with contrast tipping, garment-dyed programmes, tri-blend fabrics), the count typically ran 2-3 rounds. Standard tee CMT at Portuguese factories in our group came in at €3.20-6.50 per unit depending on volume and construction.

How Do Portuguese Factories Produce Jersey?

Portugal is one of Europe's largest jersey producers, with production concentrated in the Ave Valley knit-mill cluster spanning Guimarães, Vila Nova de Famalicão, and Santo Tirso. Roughly 70% of Portugal's knit fabric output originates in this valley (ATP, 2025), and Portuguese textile companies (12,000 in total) exported €5.5 billion in 2025 according to ATP.

Portuguese jersey production follows a specific sequence. Yarn arrives at the mill, usually combed cotton spun in Portugal or northern Spain. The mill knits the fabric on circular knitting machines (typically gauge 24-32 for standard t-shirt jersey). Finishing involves scouring to remove oils, dyeing at either yarn or piece stage, and compacting to stabilise dimensional shrinkage. The finished fabric then ships to a CMT factory for cutting and sewing.

Total lead time from order to shipped garments typically runs 4-7 weeks for standard cotton jersey, and 6-9 weeks for GOTS-certified organic. The organic delta is almost entirely fabric booking, not sewing. Certified yarn is limited-capacity and has to be reserved in advance.

Vertical integration observation: roughly 40% of the factories in our documented group either own knit-dye-finish-CMT under one roof or work with dedicated in-cluster suppliers who share bookings across the year. That vertical integration is what compresses Portuguese lead times below what horizontal Asian supply chains typically deliver. Every documented factory in our group of 80 can produce jersey. It's the baseline knit. When we route jersey production, the differentiator isn't capability, it's fit: which factory in our group is set up for the volume, GSM, and finish the brand wants.

Conclusion: What This Means for Your Brand

The practical takeaway across the sections above: match jersey to the product categories where its properties actually matter, specify it clearly on the tech pack (name the branded fibre or exact composition), and route production to a Portuguese factory in the subset that stocks the yarn or has the finishing lines built for it.

Get the spec right and the fabric becomes a repeatable, reliable choice. Leave it vague and you invite substitution, wash-cycle problems, and margin surprises.
