If you flip your pillow looking for the cool side, the pillowcase is part of the problem. It sits between your face and the pillow all night, so its fabric decides how warm and sticky that surface feels.
Cotton is breathable but absorbs sweat and can feel damp. The feel of polyester fabrics varies with weave and finish. The best pillowcases for hot sleepers are usually made of rayon from bamboo, real mulberry silk, or a cooling performance fabric that pulls heat away from your skin.
If your pillow still feels warm with a lightweight case, this guide explains how the pillow and the rest of your bedding can trap heat.
Below are 6 pillowcases we compared on Amazon across those three fabric types, from a $8 two-pack to premium silk, plus a guide to which fabric suits you.
How we picked: we shortlisted the most-reviewed cooling, bamboo and silk pillowcases on Amazon and checked each live listing for fabric, size, closure, care, ratings and review count (October 2026). We read what verified buyers say, especially about cooling and durability. Ratings and prices change, so check the listing before you buy.

The 6 Best Pillowcases for Hot Sleepers, Reviewed
1. Bedsure PureWoven Pillowcases (Rayon From Bamboo): Best Overall Bamboo
Rayon made from bamboo feels cooler to the touch than cotton and wicks moisture away from your skin. The Bedsure PureWoven set is two queen pillowcases (20″ x 30″) in a soft twill weave for about $10. It has more than 37,700 ratings and a 4.4-star average.
The envelope closure keeps the pillow in without a zipper to catch your hair. Reviewers describe it as silky and cool to the skin, and one replaced all their high-thread-count cotton pillowcases with these. Bedsure itself suggests pairing it with air conditioning for the best cooling effect, which is a fair, honest note.
What reviewers complain about: it wrinkles a little, and one buyer did not find it cool enough compared with other cooling cases.
✅ Pros
• Very low price for two
• Silky, cool-touch fabric
• Huge review base
❌ Cons
• Wrinkles
• Cooling is mild in a hot room
Not the right fit if: you want the strongest cool-to-the-touch feel. See #3.

2. BEDELITE Cooling Pillowcases (Bamboo Rayon): Cheapest
The BEDELITE set is two queen viscose-from-bamboo pillowcases for under $8. It is OEKO-TEX certified, machine washable, and has an inner flap to cover the end of the pillow.
It has a 4.4-star average across 12,400+ ratings. A very hot sleeper said it was worth every penny. Another said it helps a cooling pillow stay cool. One buyer used king cases on queen pillows and liked tucking in the extra fabric.
What reviewers complain about: one buyer felt no difference from their satin and silk cases.
✅ Pros
• Lowest price here
• OEKO-TEX certified
• Inner flap closure
❌ Cons
• Cooling varies by person
• Thin fabric
Not the right fit if: you want silk’s hair and skin benefits.

3. REST Evercool+ Cooling Pillowcases: Coolest to the Touch
The REST Evercool+ uses a nylon-spandex performance fabric that conducts heat away from your skin. REST lists a Qmax of 0.44 and says it is three times cooler than cotton. Qmax is a lab measure of how cool a fabric feels on first touch. We could not verify the test independently, but reviews back up the cool feel.
You get two king pillowcases (about 35″ x 19″). They are smooth like silk but machine washable and less likely to snag. It has a 4.4-star average across 1,200+ ratings. A self-described picky buyer said it is cooler and smoother than their Tencel sheets.
What reviewers complain about: the price, at about $67 for two. One buyer found it smooth but not cool enough to justify the cost.
✅ Pros
• Strong cool-to-the-touch feel
• Silky but machine washable
• Two king cases
❌ Cons
• Expensive
• Synthetic fabric
Not the right fit if: you prefer natural fibers.

4. Blissy 22 Momme Mulberry Silk Pillowcase: Best Premium Silk
Silk does not feel icy, but it is smooth, breathable and does not soak up sweat like cotton. It also reduces friction on hair and skin. Blissy uses 100% mulberry silk at 22 momme, a heavier, denser weight than most silk pillowcases. It is OEKO-TEX certified.
The price is for one pillowcase. We link the King. It has a 4.5-star average across 10,500+ ratings. Reviewers say it is better than satin and helped their hair and skin.
What reviewers complain about: the price for a single case, and one said the white is not a true white.
✅ Pros
• Heavy 22 momme silk
• Smooth on hair and skin
• OEKO-TEX certified
❌ Cons
• Expensive per case
• Silk needs gentle care
Not the right fit if: cooling is your only goal. Bamboo or Evercool+ is cheaper.

5. ZIMASILK 19 Momme Mulberry Silk Pillowcase: Best Value Silk
The ZIMASILK is the most reviewed pillowcase in this guide: a 4.6-star average across more than 52,000 ratings. It is 100% mulberry silk at 19 momme on both sides, for about $24 per queen case.
Several buyers did a burn test and confirmed it is real silk. Others say it is cool and smooth on the face and helped their hair after heat damage.
What reviewers complain about: the zipper seam can tear over time with machine washing and drying. One reviewer advised buyers to learn the momme ratings, since 19 momme is thinner than 22.
✅ Pros
• Real silk at a fair price
• Massive review base
• Silk on both sides
❌ Cons
• Thinner 19 momme
• Zipper wears with machine drying
Not the right fit if: you want the heaviest, longest-lasting silk.

ALASKA BEAR sells a 19 momme, grade 6A mulberry silk queen pillowcase with a hidden zipper, packaged with a scrunchie, which makes it an easy gift. It has a 4.6-star average across more than 25,000 ratings.
Reviewers confirm it is real silk on both sides. One with eczema said it helped their skin, and several with curly hair say it cut down frizz.
What reviewers complain about: lifespan. One repeat buyer said they wear out quickly unless hand washed. Another compared three silk weights and rated this the thinnest.
✅ Pros
• Real silk, gift-ready
• Hidden zipper
• Strong rating
❌ Cons
• Best hand washed
• Thinner silk
Not the right fit if: you want to machine wash and dry it every week.

Bamboo vs Silk vs Cooling Fabric
| Fabric | Feel | Best For | Care |
|---|---|---|---|
| Rayon/viscose from bamboo | Cool, silky, moisture-wicking | Hot sleepers on a budget | Machine wash |
| Mulberry silk | Smooth, breathable, not icy | Hair, skin, and mild cooling | Gentle or hand wash |
| Cooling nylon blend | Cold to the touch, slick | Very hot sleepers, night sweats | Machine wash |
| Satin (polyester) | Smooth but traps heat | Hair on a budget, not cooling | Machine wash |
Note: “satin” is a weave, usually polyester, not silk. If you want real silk, look for “100% mulberry silk” and a momme weight.
What Does Momme Mean?
Momme is the weight of silk fabric. Higher momme means thicker, more durable silk. Most silk pillowcases are 19 to 22 momme. A 22 momme case like the Blissy is heavier and tends to last longer than a 19 momme case.
A Pillowcase Helps, But Start With the Pillow
A cooling case makes the surface feel cooler, but a hot memory foam pillow underneath will still hold heat. For a bigger difference, pair a cool pillowcase with a breathable pillow. See our best cooling pillows guide and our JamRest breathable pillow cover review.
FAQ: Pillowcases for Hot Sleepers
What pillowcase material is coolest?
Cooling performance fabrics like the REST Evercool+ feel coldest to the touch. Bamboo rayon is a good, cheaper option. Silk is smooth and breathable but does not feel icy.
Are bamboo pillowcases really cooler than cotton?
Many buyers say they feel cooler and less damp. The difference is most noticeable in an air-conditioned room.
Is silk good for hot sleepers?
Silk breathes well and does not trap moisture, so it feels comfortable. Its main benefits are for hair and skin, not strong cooling.
How do you wash a silk pillowcase?
Hand wash or use a gentle cycle in a mesh bag with cool water, then air dry. Machine drying shortens its life.
Do cooling pillowcases stay cool all night?
The cool feeling is strongest when you first lie down. Fabrics that wick moisture keep you more comfortable through the night.
Bottom Line: Which Pillowcase Should You Buy?
- Want the best value? Get the Bedsure PureWoven.
- Cheapest possible? Get the BEDELITE.
- Sleep very hot? Get the REST Evercool+.
- Want premium silk? Get the Blissy 22 Momme.
- Want real silk for less? Get the ZIMASILK.
- Buying a gift? Get the ALASKA BEAR Silk.
Swap your pillowcase first. It is the cheapest change you can make, and for many hot sleepers it makes a noticeable difference.
