Common fabrics across these Henley pajama sets are 100% polyester microfleece, 100% cotton knit, and a 60% cotton / 40% polyester thermal knit blend.
Most listings are two-piece sets (top and bottoms). Some include three pieces, and a few offer additional items such as matching socks.
Henley-style tops feature button-front necks with multi-button plackets—commonly 3- or 5-button placket styles.
Size availability varies by listing. Common ranges include XS–3X and S–3X, and some listings show M–XXL (with both regular and plus options), covering petite through plus sizes.
Care varies by fabric but most listings recommend machine washing and tumble drying. Some cotton nightgowns specifically note machine wash cold and tumble dry low.
Descriptions usually note microfleece as “ultra-soft,” cotton knit as “soft” and breathable, and the 60/40 thermal knit as soft, breathable, and non-irritating—indicating varying warmth and breathability by fabric.
