Pajamas OEM Guide: Materials, Styles, and Market Opportunities in Sleepwear
The best pajama fabrics by season: cotton poplin (summer, lightweight), cotton flannel (winter, brushed warmth), bamboo jersey (year-round, 3°C cooler), and fleece (maximum warmth, loungewear). European markets prefer flannel; Australia favors bamboo for year-round comfort.
The global sleepwear market is projected to reach $18 billion by 2027, growing at 6.5% annually. For OEM buyers entering or expanding in pajamas, understanding materials, styles, and regional preferences is essential. Here’s your comprehensive pajamas OEM guide.
Key Pajama Fabrics
Key Insight: Pajama fabric selection follows seasonal and market logic: cotton poplin (80-100GSM summer, crisp and breathable), cotton flannel (180-220GSM winter, brushed for warmth), bamboo jersey (120-150GSM year-round, 3°C cooler than cotton), and fleece (200-280GSM, maximum warmth for loungewear). European markets prefer flannel for winter; Australia and Middle East favor bamboo for year-round temperature regulation; North America splits evenly between all four types depending on season.

Season
The window is short and does not extend for a late delivery

The set is usually the retail unit, so the pack format is a specification item
Compliance note
Children's nightwear carries flammability requirements in some markets
Buyer checklist
Specify the top and the bottom separately rather than the set as a whole.
Confirm both parts are graded together.
Choose the fabric structure against the season, then the fibre.
Give the weight in g/m² for the selling window.
Confirm the minimum per style and colour in sets.
List every trim individually, since each is part of the tested article.
Confirm the children's flammability requirement at the design stage.
Set the pack format, since the set is usually the retail unit.
Build the schedule backwards from the season.
Approve on a packed sample of the set.

Buyer Questions
MOQ, lead times, certification and trading terms
Around 600 sets per style and colour. The unit is a set rather than a garment, which is why the minimum is expressed in sets, and why the pack format follows the set rather than the individual piece. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
At the same fibre content, yes. Knit traps warmth and recovers better while woven allows more airflow, so the structure decides which season the range suits and the weight in g/m² decides where within it the range sits. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
The season, because the window is short and it does not extend for a late delivery. That makes the schedule a backwards calculation from the season rather than a forwards one from the order date. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
It changes both the grading and the pack. Top and bottom are graded together so the two parts fit consistently in the same size, and the pack is built around the set — which makes it a specification item rather than a packing decision. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
Children's nightwear carries flammability requirements in several markets, which belongs at the design stage with the age band rather than at testing. It is the item most likely to move a launch date in this category. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
On a packed sample of the set. The packed sample shows how the two parts read together and how the set arrives — which is what the customer actually sees, and neither is visible on a flat garment. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
