Best Fabric for Sleepwear: Top 10 Fabrics Used for Pajamas and Nightwear

The best fabric for sleepwear is the one that matches who will wear it, the season it is made for, and the price the brand needs to hit. After years of producing pajamas and nightwear in Tirupur, our default answer is simple: 100% cotton single jersey at 180 GSM for adults and kids, and 100% cotton interlock at 220 GSM for babies. This guide compares the ten sleepwear fabrics buyers ask us about most, shows which ones we produce, and explains when each one makes sense.

Which Fabric Is Best for Sleepwear? The 10 Options Compared

Sleepwear fabrics fall into two families. Knits, such as single jersey and interlock, stretch and move with the body, which is why most pajamas and lounge sets are made from them. Wovens, such as satin and flannel, hold a crisper shape and are used for classic button-front pajamas and nightgowns. So which fabric is best for sleepwear in your range? The table below covers all ten fabrics, including two we do not produce, so you can see the full picture before you brief a factory.

Our Standard Specs: 180 GSM Jersey and 220 GSM Interlock

Most of the pajamas we produce use just two constructions. For adults and kids, we use 100% cotton single jersey at 180 GSM. It is light enough to sleep in comfortably, has enough body not to look thin after washing, and takes prints well, which matters because most pajama sets carry some form of print. Our guide to single jersey fabric and how it is knitted explains the construction in detail. For kids, the same fabric keeps sets soft without adding bulk, and brands looking for sleepwear manufacturers usually start from this spec.

For babies, we move to 100% cotton interlock at 220 GSM. Interlock is a double knit, so both faces are smooth, it feels thicker and warmer, and its edges do not curl the way single jersey does. That makes it easier to sew neat necklines and cuffs and helps snaps and closures sit firmly, which is why it is the fabric we use for baby sleepsuits. Brands sourcing baby sleepwear can see our work as a baby sleep suit manufacturer.

Best Fabric for Pajamas by Season and Style

If cotton is the default, the other fabrics are there to solve specific briefs. For hot climates and summer ranges, bamboo viscose, rayon, and Tencel feel cooler against the skin and drape more loosely than cotton. For premium lounge sets, modal gives a smooth, fluid hand that customers notice immediately. For nightgowns and gift-style pajama sets, satin brings the sheen people associate with luxury nightwear, and brands developing that category often work with ladies nightwear manufacturers who handle both knits and wovens. For winter, brushed flannel is still the warmest option, and cotton-lycra jersey is the right choice for maternity sleepwear, where stretch and recovery matter more than anything else.

Two labelling points are worth knowing. Fabric made from bamboo is usually a viscose, and in the USA and the EU it should be labelled as viscose (or rayon) from bamboo, not simply “bamboo”. Our guide to bamboo clothing production covers this in more depth. Similarly, Tencel is a brand name for lyocell, and our Tencel vs lyocell buyer guide explains when you can use the name on a label.

The Print Matters as Much as the Fabric

Choosing the right fabric is only half the job, because a stiff print can undo a soft fabric. A buyer from England once asked us for pajamas with a soft-feel print, but the target price was very tight. To meet it, we chose all-over table printing. The buyer did not like the result, so we moved the order to discharge printing on a rotary machine. Discharge printing removes the dye from the fabric and replaces it with the print colour rather than laying ink on top, so the print became part of the fabric itself. The final pajamas had a soft print, properly embedded in the cotton, and that is what the buyer had wanted from the start. Our overview of printing methods used in Tirupur compares the other options.

The lesson for brands is to brief the hand feel of the print together with the fabric, and to agree on the printing method before costing, not after the first samples.

Frequently Asked Questions

What is the best fabric for sleepwear?

For most pajama lines, the best fabric for sleepwear is 100% cotton single jersey at around 180 GSM. It is soft, breathable, easy to print, and suits adults and kids across most seasons. Modal, bamboo viscose, and Tencel are softer premium options, and flannel is best for winter.

Which fabric is best for baby sleepwear?

We use 100% cotton interlock at 220 GSM for baby sleepwear. Interlock is a double knit that is smooth on both faces, slightly warmer than single jersey, and does not curl at the edges, which gives neater necklines and firmer snap placement.

Is satin or cotton better for pajamas?

Cotton is better for everyday comfort and breathability, while satin is chosen for its sheen and smooth feel in nightgowns and gift-style sets. The best fabric for pajamas therefore depends on the range: many brands run cotton as the core and satin as a premium or seasonal line.

Is bamboo a good fabric for pajamas?

Yes. Bamboo viscose feels cool and silky, which suits summer pajamas and premium lines. In the USA and the EU it should be labelled as viscose or rayon from bamboo rather than simply bamboo.

How do you get a soft print on cotton pajamas?

Discharge printing gives the softest result on cotton because it removes the dye and replaces it with the print colour instead of laying ink on the surface. We have moved pajama orders from all-over table printing to rotary discharge printing when a buyer needed a softer hand feel.
