Best Cooling Pillowcases for Hot Sleepers

These are our top picks specifically tested and selected for sleepers who run warm. Each is evaluated on breathability, sustained cooling throughout the night, and value.

#1 Pick: 300–400 TC Percale Long-Staple Cotton

The undisputed choice for most hot sleepers. Percale’s open weave creates a fabric that allows heat to dissipate throughout the night rather than building up between your face and the pillow.

Key specs to look for:

• Thread count: 300–400 TC
• Weave: Percale (not sateen)
• Fiber: Egyptian cotton, Supima, or Pima cotton
• Closure: Open-end preferred

Our rating: ★★★★★ Cooling | ★★★★★ Value | ★★★☆☆ Softness (crisp feel)

#2 Pick: Bamboo Lyocell (250–350 GSM)

If you want the cooling of percale plus superior moisture-wicking, bamboo lyocell is the step up. Particularly good for sleepers in humid climates or those who sweat even lightly during sleep.

Key specs to look for:

• Material: Bamboo lyocell (not viscose)
• GSM: 250–350
• Certifications: OEKO-TEX or Bluesign

Our rating: ★★★★★ Cooling | ★★★★★ Moisture-wicking | ★★★★☆ Softness

#3 Pick: Eucalyptus Tencel™ Pillowcases

The premium plant-fiber option. Tencel’s closed-loop manufacturing produces an exceptionally consistent, ultra-soft, and cooling fiber. Slightly more expensive than bamboo but worth it for the elevated feel.

Our rating: ★★★★★ Cooling | ★★★★★ Sustainability | ★★★★★ Softness

#4 Pick: 22 Momme Mulberry Silk (for the Luxury Sleeper)

If budget isn’t a concern, silk delivers unmatched thermoregulation and feel. Naturally adapts to body temperature; feels cool to the touch regardless of room temperature.

Our rating: ★★★★★ Feel | ★★★★☆ Cooling | ★★☆☆☆ Care Simplicity

What to Avoid

• Sateen cotton — denser weave traps heat; not suitable for hot sleepers
• Polyester or microfiber — significantly warmer than natural fibers
• High TC (600+) sateen — the worst combination for heat retention
• Flannel — designed for warmth; completely wrong for hot sleepers
