There is an uncomfortable truth about sleeping in summer: the material you wear matters more than the mattress. Poorly chosen men’s pajama shorts — synthetic, stiff, non-ventilated — can ruin hours of rest even when everything else is perfect. This guide was created so that never happens.
At El Búho Nocturno, we have been perfecting men’s nightwear for over a decade, rooted in the Spanish textile tradition of the 60s. Here, there are no compromises: every seam, every material, and every size is designed so you sleep better.
1. Why material is key in summer
During sleep, body temperature naturally drops by 1–2 degrees. If the material blocks this, the body fights itself, night sweating increases, and rest quality deteriorates.
- True breathability: natural fibers allow air circulation and wick away moisture. Synthetics trap it.
- Active thermoregulation: cotton absorbs up to 27% of its weight in moisture without feeling wet on the skin.
- Touch that improves over time: unlike synthetics, cotton softens with every wash.
- Hypoallergenic: does not irritate sensitive skin and does not generate static electricity.
In our collection of men’s pajama shorts, 100% of the models are made from cotton or high-cotton blends.
2. Poplin 100% cotton vs cotton jersey: the ultimate comparison
| Feature | 🔵 Poplin 100% Cotton | ⚫ Jersey 85% Cotton |
|---|---|---|
| Touch | Stiff, smooth, classic | Soft, stretchy, enveloping |
| Coolness | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Elasticity | None (flat weave) | High (fits the body) |
| Buttons | ✅ Yes, two concealed buttons | ❌ No (elastic waistband) |
| Pockets | ✅ Two side pockets | ✅ Two side pockets |
| Pattern | Classic check | Solid (gray or navy) |
| Sizes | M – 3XL | M – 3XL |
| Price from | 15 € | 30 € |
| Perfect fit | A classic that doesn’t sacrifice style | Those who prioritize maximum comfort |
Verdict: if you sleep in a fixed position and appreciate traditional checks, choose poplin. If you move a lot or seek the coolest feeling, cotton jersey is unmatched.
3. 6 details that make a difference
- Opening with two covered buttons — on all poplin models. Fabric flap eliminates direct contact of buttons with the skin.
- Elastic waistband with tape made of the same material — not ordinary elastic, but personalized tape. No marks on the skin after hours of sleep.
- Two side pockets on all models — without exception.
- Regular, loose fit — wide legs for maximum freedom of movement.
- Embroidered logo — not printed. The embroidery does not wear out with washing.
- Strict quality control — every product checked from material to finished garment.
4. Size guide M–3XL
All models are available in sizes M, L, XL, XXL, and 3XL at no extra cost. Regular and loose fit: if you are between two sizes, choose the larger one for more comfort while sleeping.

💡 Tip: jersey models have more stretch — if you are between sizes, you can choose the smaller one without losing comfort.
5. Colors and styles
- Checkered poplin: navy, classic blue, light blue, green, red, gray, and white.
