There is an uncomfortable truth about sleeping in summer: the fabric you wear matters more than the mattress. Poorly chosen men's pyjama shorts — synthetic, stiff, with no ventilation — can ruin hours of sleep even when everything else is perfect. This guide exists so that never happens to you.
At El Búho Nocturno, we have been perfecting men's nightwear for over a decade, with roots in the Spanish textile tradition of the 1960s. No compromises here: 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 by 1–2 degrees. This is an essential physiological mechanism: if the fabric blocks it, the body fights against itself, night sweating increases and sleep quality collapses.
Cotton is the only fabric that supports this process rather than hindering it:
- Real breathability: natural fibres allow air circulation and wick away moisture. Synthetics trap it.
- Active thermoregulation: cotton absorbs up to 27% of its weight in moisture without feeling damp on the skin.
- A feel that improves over time: unlike synthetics, cotton softens with every wash.
- Hypoallergenic: does not irritate sensitive skin and generates no static electricity.
In our collection of men's pyjama shorts, 100% of the styles are made from cotton or high-cotton-content blends.
2. 100% poplin cotton vs cotton jersey: the definitive comparison
Two fabric families, two distinct experiences. Neither is better in absolute terms: the right choice depends on your sleeping style and tactile preferences.
| Feature | 🔵 100% Poplin Cotton | ⚫ 85% Cotton Jersey |
|---|---|---|
| Feel | Firm, smooth, classic | Soft, stretchy, enveloping |
| Coolness | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Stretch | None (flat weave) | High (adapts to the body) |
| Fly | ✅ Yes, two covered buttons | ❌ No (elasticated waist) |
| Pockets | ✅ Two side pockets | ✅ Two side pockets |
| Pattern | Classic check | Plain (grey or navy) |
| Sizes | M – 3XL | M – 3XL |
| Price from | £15 | £28 |
| Ideal for | The classic man who won’t compromise on style | Those who prioritise maximum comfort |
Verdict: if you sleep in a fixed position and appreciate the traditional check style, choose poplin. If you move around a lot during sleep or want the coolest possible feel, cotton jersey has no rival.
3. The 6 details that make the difference
The difference between men's pyjama shorts that last one summer and those that last ten years is not the price: it is the details. Here are the ones that define El Búho Nocturno quality:
- Two-button covered fly — on all poplin styles. The fabric flap eliminates direct button contact with the skin.
- Elasticated waistband with matching fabric tape — not a generic elastic, but a custom tape in the same fabric. No marks on the skin after hours of sleep.
- Two side pockets on every style — without exception. Because men's pyjama shorts are also loungewear.
- Regular fit, generously cut — wide legs designed for total freedom of movement.
- Embroidered logo — not printed. Embroidery does not deteriorate with washing. Print does.
- Thorough quality control — every piece checked from fabric to finished product.
4. Size guide M–3XL: how to choose
All El Búho Nocturno men's pyjama shorts are available in M, L, XL, XXL and 3XL at no extra cost. The fit is regular and generous: if you are usually between two sizes, choose the larger for more comfort during sleep.
Consult our full size guide with exact waist and hip measurements.
💡 Tip: cotton jersey styles have more stretch, so if you are on the border between two sizes you can choose the smaller one without losing comfort.
5. Colours and styles: from classic check to minimalist plain
The palette of our men's pyjama shorts summer 2026 collection covers every preference:
- Poplin check: navy, classic blue, sky blue, green, red, grey and white.

7. Care to make them last for years
Good men's pyjama shorts, properly cared for, last a decade. The instructions are simple:
- Machine wash at 30°C, normal or delicate cycle.
- Air dry — preserves shape, colour and fabric elasticity.
- Do not use bleach or aggressive fabric softener.
- Do not tumble dry at high temperature — poplin shrinks.
- Poplin maintains its structure and colour definition wash after wash.
- Cotton jersey retains its stretch with basic care.
