When the heat arrives, choosing the right men's summer pajama makes the difference between a restful night's sleep and tossing and turning. In this complete guide, we explain which materials work best, which cuts are coolest, and how to get the right size for summer 2026.
Why does summer pajamas matter?
Body temperature naturally drops during sleep. If your sleepwear is not breathable, the body cannot regulate this temperature drop well, and you wake up sweaty, uncomfortable, and with interrupted sleep. A good men's summer pajama in cotton acts as a natural thermal regulator: it absorbs moisture, allows air circulation, and maintains a stable temperature throughout the night.
The best materials for summer pajamas
100% cotton poplin — the king of summer
Cotton poplin is the most recommended fabric for summer for several reasons:
- Breathable and absorbent — efficiently removes moisture from the skin.
- Soft to the touch — does not irritate sensitive skin or cause chafing.
- Great color definition — checkered and striped prints maintain their vibrancy wash after wash.
- Durable — withstands frequent washing without losing shape or softness.
At El Búho Nocturno all our short summer pajamas are made from 100% cotton poplin or 160 g/m² cotton knit, the ideal weight for warm nights.
Cotton knit — maximum comfort and elasticity
The cotton knit (jersey knit) is more elastic than poplin, making it especially comfortable for those who move a lot during sleep. Without a fly, with an elastic waistband and wide legs — the freest and coolest option for summer.
What to avoid in summer?
- Pure polyester — does not breathe, traps heat, and generates static electricity.
- Flannel and velvet — winter fabrics, too warm for June-September.
- Mixed synthetic fabrics — reduce the breathability of cotton.
Short pajamas vs long pajamas in summer: which to choose?
Summer short pajamas
The short pajama (short-sleeve shirt + shorts) is the coolest option and the best seller from June to September. Advantages:
- Maximum ventilation in legs and arms.
- Ideal for temperatures above 22°C in the bedroom.
- More versatile — also serves as loungewear.
Our models of short summer Mens Pajama are available in checkered poplin with judo or placket collar, and in solid knit. Sizes M to 5XL from €25.
Long Mens Pajama for transitional seasons
If you sleep with air conditioning or in cooler temperature areas at night, a long poplin Mens Pajama may be more comfortable than the short one. Fine poplin is cool enough for summer nights with air conditioning.
Size guide for summer Mens Pajamas
One of the most common mistakes when buying a Mens Pajama is choosing the wrong size. At El Búho Nocturno the cut is regular loose — designed for maximum comfort during rest, not for a tight fit.
| Size | Equivalent | Chest (cm) | Waist (cm) |
|---|---|---|---|
| M | Size 3 | 96–100 | 82–86 |
| L | Size 4 | 100–104 | 86–90 |
| XL | Size 5 | 104–108 | 90–94 |
| XXL | Size 6 | 108–116 | 94–102 |
| XXXL | Size 7 | 116–124 | 102–110 |
| 4XL | Size 8 | 124–132 | 110–118 |
| 5XL | Size 9 | 132–140 | 118–126 |
Tip: if you hesitate between two sizes, choose the larger one. The Mens Pajama should fit loosely to avoid restricting movement during sleep.

How to care for your summer Mens Pajama to last for years
- Wash at 30°C on a delicate or normal cycle. Cotton withstands higher temperatures well, but at 30°C it better preserves color and shape.
- Do not overuse fabric softener — it reduces cotton's absorbency over time.
- Air dry whenever you can. High-temperature drying shrinks cotton and wears out the fibers.
- Do not use bleach — it destroys cotton fibers and fades prints.
- Rotate between 2-3 pajamas — letting the garment rest between washes significantly extends its useful life.
Summer pajama as a gift for men
A quality summer pajama is one of the most practical and appreciated gifts for men. Unlike street clothes, the recipient always uses it — and appreciates it every night. Some tips to get it right:
- If you don’t know the exact size, choose one size above what you think — the loose cut is forgiving.
- The classic checkered patterns in blue and white are the most timeless and the most liked.
- Pair the pajama with some woven boxers for a complete gift from €37.
Frequently asked questions about men's summer pajamas
What is the best fabric for a summer pajama?
The 100% cotton poplin is the best fabric for summer: breathable, soft, durable, and with great color definition. Cotton knit is a more elastic and comfortable alternative for those who prefer unstructured fabrics.
Is the short or long pajama better in summer?
It depends on your bedroom temperature. If you sleep without air conditioning with temperatures above 22°C, the short pajama is clearly better. If you have air conditioning or sleep in cool areas, the long poplin pajama is also a valid option.
What size pajama should I choose?
Choose your usual size or one size up. The cut of our pajamas is regular loose — if you are between two sizes, the larger one is always the most comfortable option for sleeping.
Can summer pajamas be used as loungewear?
Yes. The classic design of our poplin pajamas makes them perfectly suitable for staying at home, going out for the newspaper, or receiving informal visitors. They are truly multipurpose garments.
How much does a good summer pajama cost?
A quality summer pajama in 100% cotton poplin costs between €25 and €45. Below that price, the fabric quality usually suffers. Above it, you are paying for premium materials like bamboo or silk.
