Men's Pajama Shorts: The Complete Guide to Staying Cool While Sleeping in Summer (2026)

There is an uncomfortable truth about summer sleep: the fabric you wear matters more than the mattress. Poorly chosen men's pajama shorts — synthetic, stiff, without ventilation — can ruin hours of rest even if everything else is perfect. This guide exists so that this does not happen to you.

At El Búho Nocturno, we have been perfecting men's nightwear for over a decade, rooted in the Spanish textile tradition of the 1960s. Here there are no compromises: every knit, 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. 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 moisture evacuation. 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 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 of cotton or high-cotton blend.

2. 100% Cotton Poplin 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, smooth, classic Soft, stretchy, enveloping
Freshness ⭐⭐⭐⭐ ⭐⭐⭐⭐⭐
Elasticity None (flat fabric) High (fits the body)
Buttoning ✅ Yes, two covered buttons ❌ No (elastic waistband)
Pockets ✅ Two side pockets ✅ Two side pockets
Pattern Classic checks Solid color (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 the poplin. If you move a lot during sleep or seek the coolest possible feel, cotton jersey is unbeatable.

3. The 6 details that make the difference

The difference between men's pajama shorts that last one summer and others that last ten years is not in the price: it’s in the details. Here are those that define El Búho Nocturno quality:

  1. Two-button fly covered by fabric — present on all poplin models. The fabric flap eliminates direct contact of the buttons with the skin.
  2. Waist elastic with tape of the same fabric — not a generic elastic, but a personalized tape of the same fabric. No marks on the skin after hours of sleep.
  3. Two side pockets on all models — without exceptions. Because pajama shorts are also loungewear.
  4. Regular loose fit — wide legs designed for maximum freedom of movement.
  5. Embroidered logo — not printed. Embroidery does not deteriorate with washing. Printing does.
  6. Thorough quality control — every garment checked from fabric to finished product.

4. Size guide M–3XL: how to choose

All models of men's pajama shorts by El Búho Nocturno are available in M, L, XL, XXL, and 3XL at no extra cost. The fit is regular loose: if you usually fall between two sizes, choose the larger one for more comfort while sleeping.

Check the complete size guide with exact waist and hip measurements.

💡 Tip: cotton jersey models have more elasticity, so if you are between two sizes, you can choose the smaller size without losing comfort.

5. Colors and styles: from classic checks to minimalist solids

The color palette of the men's pajama shorts summer 2026 collection covers all profiles:

  • Checked poplin: navy blue, classic blue, light blue, green, red, gray, and white.
  • Solid jersey: anthracite gray and navy blue. Minimalism applied to summer pajamas.

7. Care and maintenance to make them last for years

Good quality men’s pajama shorts, well cared for, last a decade. The instructions are simple:

  • Machine wash at 30 °C, normal or delicate cycle.
  • Air drying — preserves the shape, color, and elasticity of the fabric.
  • Do not use bleach or harsh fabric softener.
  • Do not tumble dry at high temperature — it shrinks poplin.
  • The poplin maintains its structure and color definition wash after wash.
  • The cotton jersey retains its elasticity with basic care.
