Definition

Jersey fabric is a soft, stretchy knit fabric with a smooth right side and a looped, slightly textured back. It is the standard knit used to make t-shirts, and it can be produced from cotton, polyester, or blends of the two. Because it stretches and drapes well, jersey is comfortable to wear and easy to decorate, which makes it the workhorse material across casual apparel.

Definition

Jersey is made by knitting a single set of yarns into interlocking loops rather than weaving threads over and under each other. This single-knit structure is what gives the fabric its give and its lightweight feel. The most familiar example is the plain cotton tee: pick up any basic crew-neck t-shirt, look at the smooth outer surface and the faintly ribbed inner surface, and you are holding single jersey.

How jersey fabric works

Jersey is a weft knit produced on a circular knitting machine. A single yarn forms a continuous row of loops, and each loop hooks into the row below it. The face of the fabric shows neat vertical columns of stitches, while the back shows horizontal loops, so the two sides look and feel different. This single-knit construction is lighter and stretchier than woven cloth, and it stretches mainly across the width rather than the length. Add a small amount of elastane and you get the four-way stretch used in fitted and athletic styles.

There are two main types. Single jersey uses one needle bed and gives you the classic thin, drapey t-shirt fabric with a clear right and wrong side. Double jersey is knitted on two needle beds, so both sides look the same, the fabric is thicker and more stable, and the edges do not curl. Interlock is a popular double-knit variant that is smooth on both faces and holds its shape well, which suits polos and structured pieces.

Fiber choice shapes how the fabric performs. Cotton jersey is breathable and soft, polyester jersey is durable and wicks moisture, and cotton-poly blends balance comfort with shape retention. Weight is measured in grams per square meter (GSM): lighter jersey around 140 to 160 GSM feels airy, while heavier jersey from 180 to 220 GSM feels premium and lasts longer. One quirk to plan for is curling, since the cut edges of single jersey roll toward the back. Jersey takes most decoration methods well, including screen printing, DTG, and heat transfer, with smoother, higher-GSM fabric giving the cleanest print results.

Jersey fabric in branded merch

  1. T-shirts and long-sleeves. Single jersey is the default fabric for branded tees. It is cost-effective, comfortable, and a clean canvas for logos, so it is the first product most teams order for events, onboarding kits, and giveaways.
  2. Polos and dresses. Heavier double jersey and interlock hold their shape, resist curling, and look more refined, which makes them ideal for branded polos, retail-quality apparel, and uniform programs where structure matters.
  3. Soft promo items. Jersey is also used for items like beanies, headbands, and lightweight totes where a soft hand-feel and a little stretch improve the experience of wearing or carrying branded merch.

Jersey fabric is a single-knit textile with a smooth face and looped back that stretches in width, giving it the soft drape and comfort that define the everyday t-shirt.

5 tips to elevate your Jersey fabric strategy

TipSteps
Match weight to useChoose 140 to 160 GSM for budget tees and 180 GSM or more for premium, longer-lasting pieces.
Plan for curlingExpect single jersey edges to roll, and use double jersey or interlock when you need flat, stable hems.
Pick fiber by goalUse cotton for softness, polyester for performance, and blends when you want both comfort and shape retention.
Test your printOrder a sample so you can check how your decoration method sits on the jersey before a full run.
Consider combed cottonSpecify combed or ringspun cotton jersey for a smoother surface and crisper prints.

Key Terminologies

Single jersey - the lightweight single-knit jersey used for most basic t-shirts, with a distinct right and wrong side.
Double jersey / interlock - a thicker double-knit jersey that looks the same on both sides and resists curling.
GSM - grams per square meter, the measure of fabric weight that signals how light or heavy a jersey feels.
Combed cotton - cotton fibers combed to remove short strands, giving jersey a smoother, stronger surface.
Ringspun cotton - cotton spun into finer, softer yarn that produces a smoother jersey for cleaner decoration.

Frequently Asked Questions

Is jersey fabric the same as cotton?

No. Jersey describes how the fabric is knitted, not what it is made from. Jersey can be cotton, polyester, or a blend, so cotton is one common fiber used to make jersey rather than a synonym for it.

Why do the edges of jersey curl?

Single jersey curls because its loops create uneven tension between the front and back of the fabric, pulling cut edges toward the looped side. Double jersey and interlock are balanced on both faces, so they lie flat.

What weight of jersey is best for a t-shirt?

For everyday branded tees, 150 to 180 GSM is a reliable range. Lighter weights feel airy and cost less, while heavier weights feel more premium and hold up better over many washes.

Does jersey fabric shrink?

Cotton jersey can shrink slightly after the first wash unless it has been pre-shrunk. Polyester and blended jerseys are more stable, which is why blends are popular for items that need to keep their fit.

Can you print logos on jersey?

Yes. Jersey works with screen printing, direct-to-garment, and heat transfer. Smoother, higher-GSM jersey and combed cotton give the cleanest, most durable results.
