Sleeping well depends on a delicate balance: a stable temperature, controlled moisture levels and a gentle, comfortable touch against the skin. The fabric of your pyjamas directly influences all three factors.

The right fabric helps your body maintain its natural temperature throughout the night. The wrong one can trap heat, retain moisture or create a heavy, uncomfortable feeling that disrupts deep sleep phases.

Thermoregulation: how your body manages heat while you sleep

During sleep, the body lowers its core temperature to initiate and maintain rest. For this process to work correctly, the fabric must:
• Allow air circulation
• Absorb and release moisture
• Prevent heat build-up
• Move with the skin without friction

Modal and 100% Mercerized cotton excel in these areas, each offering a unique thermal behaviour.

Modal: freshness, supreme softness and advanced moisture management

Modal, a natural-based cellulosic fibre, is known for its ability to:
• Regulate moisture better than most natural fibres
• Maintain a constant fresh sensation
• Breathe without causing cooling
• Offer a silky feel ideal for sensitive skin

This makes it one of the best fabrics for sleeping for those who:
• Get warm easily
• Experience night sweats
• Want a soft, irritation-free touch
• Prefer a lightweight, fluid and stable garment

Studies from Textile Exchange show that Modal outperforms cotton in moisture absorption and humidity control, creating a stable microclimate around the body.

100% Mercerized cotton: lightness, breathability and natural thermal balance

100% Mercerized cotton, one of the noblest natural fibres, stands out for its extremely fine, long-staple structure. Its key qualities include:
• High breathability
• Excellent thermal regulation
• Natural softness and durability
• Comfort in every season

It does not trap heat or create excessive insulation, allowing the body to maintain a stable temperature. It is ideal for those who want:
• A lightweight feel
• A long-lasting and resistant garment
• A pure natural fibre that breathes exceptionally well
• A fabric suitable for sleeping all year round

Modal vs 100% Mercerized cotton: which fabric should you choose based on your nightly sensations?

✔ If you get warm or wake up damp:
→ Modal (excellent humidity control and all-night freshness)

✔ If you want absolute natural purity:
→ 100% Mercerized cotton

✔ If you have sensitive skin:
→ Modal (silky softness)
→ 100% Mercerized cotton (pure fibre without irritants)

✔ If you need a year-round pyjama:
→ Both work perfectly:

• 100% Mercerized cotton (naturally balanced warmth)

✔ If you prefer a fluid, soft, minimal feel:
→ Modal

✔ If you prefer lightness, structure and natural breathability:

What to consider when choosing the best fabric for sleeping

• Do you get warm at night?
• Do you need extreme softness on the skin?

Your answers point clearly toward the fabric that fits your needs.
