The softest fabric for pajamas is welsoft — an ultra-soft, velvety micro-polyester knit specifically developed for skin-contact comfort. For warmer-weather pajamas, cotton jersey is the lighter, more breathable choice; for cold-weather sets, polar fleece adds extra warmth.
Comparing Pajama Fabrics
| Fabric | GSM | Season |
|---|---|---|
| Welsoft (microfleece) | 240–250 | Year-round, coldest sleep comfort |
| Cotton jersey | 150–180 | Spring/summer |
| Polar fleece | 270–280 | Winter |
Welsoft's finer micro-yarn gives it a noticeably thinner, softer pile than standard polar fleece, with better drape — which is why it's the preferred fabric for pajamas, robes and loungewear rather than outerwear-grade fleece.
