Jersey fabric is a knitted textile made by looping one continuous yarn through itself on a single set of needles, which is why it's also called single knit. It has a smooth, slightly ribbed face, a looped back, natural stretch, and a soft drape that makes it the standard fabric for T-shirts and casual clothing.

"Jersey knit" refers to the same weft-knit construction as jersey fabric — the terms are used interchangeably. It describes how the fabric is built (looped stitches) rather than what it's made from, so you'll see cotton jersey knit, polyester jersey knit and blended jersey knit fabrics.

Jersey material is another common name for jersey fabric, most often used when people are talking about fiber content — for example, "cotton jersey material" or "poly-blend jersey material." Structurally, it's the same single-knit fabric.

Jersey is a knitted fabric, not a woven one. It's built from interlocking loops rather than threads crossing over and under each other, which gives it stretch and a soft hand that most woven fabrics don't have.

Jersey can be knitted from almost any yarn: 100% cotton, polyester, viscose/rayon, modal, wool or linen, and blends of these — often with a small percentage of elastane for extra stretch. The fiber changes how the fabric feels and performs, but not the basic knit structure.

There's no single required material — jersey describes a knit construction that can be made from cotton, polyester, rayon/viscose, modal, wool or blends. Cotton and cotton-blend jersey are the most common for everyday apparel.

Jersey is produced on a circular or flat weft-knitting machine using a single set of needles, which pulls one yarn into a continuous series of interlocking loops. This single-needle-bed process is what gives plain jersey its distinct front and back faces.

Yes. Jersey is one of the most common knit fabrics, specifically a weft knit, as opposed to a woven fabric or a warp knit like tricot.

Single jersey is the most basic jersey construction, knitted on one needle bed, giving a smooth flat-stitch face and a looped, textured back. It's lightweight, stretchy, and the type most people picture when they hear "jersey."

Double jersey is knitted on two sets of needles instead of one, producing a thicker, more stable fabric that looks similar on both sides. It holds its shape better than single jersey and is common in structured knitwear.

Interlock is a type of double jersey where the loops from both needle beds interlock directly with each other, creating a smooth, identical face on both sides with no visible ribs. It's heavier, less prone to curling at the edges, and often used for polos and higher-end T-shirts.

Standard (single) jersey is thinner, more stretchy, and curls at cut edges, while interlock is thicker, more stable, and lies flat. Interlock also tends to feel the same on both sides, whereas single jersey has a distinct front and back.

Yes — the looped knit structure gives jersey natural stretch, usually more from side to side than from top to bottom. How much it stretches, and how well it bounces back, depends on the fiber content and whether elastane has been added.

Generally yes, especially cotton and cotton-blend jersey, because the open loop structure lets air move through more easily than a tightly woven fabric. Breathability drops somewhat with heavier weights or fully synthetic blends.

Cotton and cotton-blend jersey can shrink a few percent after the first wash if it wasn't pre-shrunk during finishing, while polyester and poly-blend jersey are far more shrink-resistant. Washing in cool water and air- or low-heat drying reduces shrinkage significantly.

Jersey is a reliable, versatile fabric for apparel — its quality depends more on fiber content, knit density and GSM than on the fact that it's "jersey." A well-specified cotton or cotton-blend jersey at the right weight performs very well for everyday clothing.

Cotton jersey is jersey knitted from 100% cotton yarn (or very high cotton content), prized for its softness, breathability and natural feel. It's the most widely used jersey type for T-shirts, everyday dresses and baby clothing.

Modal jersey is knitted from modal, a semi-synthetic fiber made from beech tree cellulose, giving it a silky drape, excellent softness and good moisture management. It's often blended with cotton or spandex for loungewear and fitted basics.

Slub jersey is knitted from yarn that has intentional thick-and-thin irregularities (slubs), creating a subtly textured, uneven surface. It's popular for casualwear that wants a relaxed, textured look rather than a perfectly smooth finish.

The main categories are construction types (single jersey, double jersey, interlock, rib) and fiber/finish types (cotton, polyester, modal, viscose/rayon, wool, slub, matte, and stretch/cotton-spandex jersey), plus specialty variants like scuba and ponte. Most garments combine one construction type with one fiber choice.

Jersey is used for T-shirts, casual dresses, loungewear, underwear, baby clothing, sleepwear and lightweight layering pieces — essentially anywhere a soft, stretchy, comfortable fabric is needed. Heavier jersey and interlock are also used for polos and structured knitwear.

Jersey blended with polyester and elastane works well for lighter activewear like training tees and casual athleisure, since it stretches and breathes well. For high-performance activewear, brands often move to specialized moisture-wicking knits rather than plain cotton jersey.

There's no single "correct" GSM — lightweight jersey (roughly 120–160 GSM) suits warm-climate tees and layering, standard tee-weight jersey (roughly 160–200 GSM) covers most everyday apparel, and heavier jersey or interlock (200 GSM and up) suits structured or premium garments. The right weight depends on the garment type, drape and market position.

Start with the garment type and end use, then decide on fiber blend (cotton for softness and breathability, poly blends for durability and shape retention), knit construction (single jersey for stretch, interlock for structure), and GSM. A manufacturing partner can also help you test for shrinkage, pilling and colorfastness before committing to a production run.
