• Better temperature comfort for a more stable, comfortable night
• Softer feel can help you relax more easily at bedtime
• Less friction may feel gentler and less irritating on sensitive skin
• Good moisture handling can help reduce a “clammy” feeling
• “Luxury comfort” effect: your sleep environment matters for restful sleep

• “Improves sleep quality” can sound like a guarantee. Safer wording is: “supports a more comfortable sleep environment” or “can help you sleep more comfortably”.
• Temperature comfort depends on room temperature, duvet/blanket, pajamas, and personal preference—avoid absolute claims like “stays cool all night.”
• Friction & irritation are personal and depend on sensitivity and care/washing. Use “may” / “can” instead of promises.

• Better temperature comfort: sleep-hygiene guidance commonly recommends keeping the bedroom cool at night (often roughly in the 60–67°F / ~15–19°C range) to support better sleep.
• Sleep environment matters: expert sleep guidance highlights that a calm, comfortable bedroom (cool, dark, quiet) and comfortable bedding can support better rest.
• Less friction & irritation: soft, breathable cotton is commonly recommended for sensitive skin because it’s gentle, breathable, and helps with sweat/comfort.
• Moisture handling: cotton is often noted for absorbing sweat and allowing skin to “breathe,” which can feel more comfortable if you run warm at night.
