There is an uncomfortable truth about sleeping in summer: the fabric 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 exists so that never happens to you.
At El Búho Nocturno, we have perfected men's nightwear for over a decade, rooted in the Spanish textile tradition of the 60s. Here, there are no compromises: every stitch, every fabric, and every size is designed so you sleep better.
1. Why fabric is essential in summer
During sleep, body temperature naturally drops 1–2 degrees. It is an essential physiological mechanism: if the fabric blocks it, the body fights itself, night sweating increases, and rest quality collapses.
Cotton is the only fabric that supports this process instead of hindering it:
- Real breathability: natural fibers allow air circulation and wick away moisture. Synthetics retain 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 each wash.
- Hypoallergenic: does not irritate sensitive skin and does not generate static electricity.
In our men's pajama shorts collection, 100% of the models are made from cotton or high-cotton blends.
2. Poplin 100% cotton vs cotton jersey: the ultimate comparison
Two fabric families, two distinct experiences. Neither is absolutely better: the right choice depends on your sleep style and tactile preferences.
| Feature | 🔵 Poplin 100% Cotton | ⚫ Jersey 85% Cotton |
|---|---|---|
| Touch | Firm, plain, classic | Soft, stretchy, enveloping |
| Freshness | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Elasticity | None (plain fabric) | High (fits the body) |
| Buttons | ✅ Yes, two covered buttons | ❌ No (elastic waistband) |
| Pockets | ✅ Two side pockets | ✅ Two side pockets |
| Pattern | Classic plaid | Plain (gray or navy blue) |
| Sizes | M – 3XL | M – 3XL |
| Price from | 15 € | 30 € |
| Ideal profile | The classic that never sacrifices style | For those who prioritize maximum comfort |
Verdict: if you sleep in a fixed position and appreciate the traditional checked style, choose poplin. If you move a lot during sleep or seek the coolest possible feel, cotton jersey is unrivaled.
3. The 6 details that make the difference
The difference between men’s pajama shorts that last one summer and those that last ten years is not the price: it’s in the details. Here are the ones that define El Búho Nocturno quality:
- Opening with two fabric-covered buttons — on all poplin models. The fabric covering prevents direct contact of the buttons with the skin.
- Waist elastic with fabric tape — not a generic elastic, but a custom tape made from the same fabric. No marks on the skin after hours of sleep.
- Two side pockets on all models — without exception. Because pajama shorts are also loungewear.
- Regular loose cut — wide legs designed for maximum freedom of movement.
- Embroidered logo — not printed. Embroidery does not deteriorate with washing. Printing does.
- Thorough quality control — every piece checked from fabric to finished product.
4. Size guide M–3XL: how to choose
All men’s pajama shorts models by El Búho Nocturno are available in M, L, XL, XXL, and 3XL at no extra cost. The cut is regular and loose: if you usually fall between two sizes, choose the larger one for greater comfort while sleeping.
Check our complete size guide with exact waist and hip measurements.
💡 Tip: cotton jersey models have greater elasticity, so if you are between two sizes, you can choose the smaller one without losing comfort.
5. Colors and styles: from classic checks to minimalist plain
The palette of the men’s pajama shorts summer 2026 collection covers all preferences:

7. Care to last for years
Good men's pajama shorts, well cared for, last a decade. The instructions are simple:
- Machine wash at 30 °C, normal or delicate cycle.
- Air dry — preserves the shape, color, and elasticity of the fabric.
- Do not use bleach or harsh fabric softener.
- Do not tumble dry at high temperature — poplin shrinks.
- The poplin maintains its structure and color definition wash after wash.
- The cotton jersey retains its elasticity with basic care.
