What Bedsheet Fabric Sleeps the Coolest? A Guide to the Best Summer Bedsheet Materials

When the temperature rises, a good night’s sleep often depends on one simple thing: your bedsheet. Not all bedsheet fabrics are created equal when it comes to staying cool and comfortable in the summer. In this guide, we’ll explore the coolest bedsheet fabrics for hot sleepers and warm weather, including their pros and cons, so you can choose the best material for your needs.

What Makes a Bedsheet “Cool”?

The coolest bedsheet fabrics have a few things in common:

• Breathability: Allows air to circulate and body heat to escape.
• Moisture-wicking: Pulls sweat away from the skin to keep you dry.
• Lightweight: Feels airy and soft, not heavy or clingy.

1. Linen – The Champion of Summer Bedding

Why it sleeps cool:

Linen is made from the flax plant and is naturally breathable, moisture-wicking, and temperature-regulating. It has a loose weave that lets air flow freely.

Pros:

• Extremely breathable
• Gets softer with each wash
• Hypoallergenic and antimicrobial
• Durable and long-lasting

Cons:

• Can feel rough at first
• Wrinkles easily
• Typically more expensive than cotton

Best for: Hot sleepers and those looking for a luxury, eco-friendly option.

2. Cotton (Especially Percale Weave)

Why it sleeps cool:

Cotton is a classic fabric, but not all weaves are equal. Percale cotton has a crisp, matte finish and a tight weave that feels cool to the touch.

Pros:

• Highly breathable and soft
• Affordable and widely available
• Easy to care for

Cons:

• Not as moisture-wicking as linen or bamboo
• Some weaves (like sateen) can trap heat

Best for: Anyone looking for comfortable, breathable sheets at a moderate price.

3. Bamboo (Viscose from Bamboo)

Why it sleeps cool:

Bamboo-derived fabrics are ultra-soft and known for their excellent moisture-wicking abilities and natural temperature regulation.

Pros:

• Silky-smooth texture
• Naturally hypoallergenic
• Wicks away moisture better than cotton
• Eco-friendly when sustainably made

Cons:

• Can be more expensive than cotton
• Manufacturing process can vary (choose OEKO-TEX® certified for safety)

Best for: Sweaty sleepers and those with sensitive skin.

4. Tencel (Lyocell)

Why it sleeps cool:

Tencel is made from eucalyptus wood pulp. It has a smooth, breathable structure that regulates temperature and resists moisture buildup.

Pros:

• Ultra-soft and lightweight
• Great at moisture absorption
• Eco-friendly closed-loop manufacturing
• Resistant to bacteria and odor

Cons:

• Pricier than basic cotton
• Can pill over time if not cared for properly

Best for: Eco-conscious shoppers and those who love silky sheets.

5. Blends (Cotton-Linen, Cotton-Bamboo, etc.)

Why they can sleep cool:

Blends combine the best features of multiple fabrics—such as the softness of cotton and the breathability of linen.

Pros:

• Often more affordable than 100% linen or bamboo
• Balanced texture and breathability
• Less likely to wrinkle

Cons:

• Quality depends on the ratio and weave
• May not be as cooling as pure materials

Best for: People who want a balance between comfort, coolness, and price.

Fabrics to Avoid for Summer

• Flannel – Too heavy and warm
• Microfiber – Often traps heat and doesn’t breathe well
• Polyester – Not breathable or moisture-wicking

Final Thoughts: What’s the Coolest Bedsheet Fabric?

If your top priority is sleeping cool, linen is hard to beat for airflow and moisture-wicking. For a silky-smooth and breathable feel, bamboo or Tencel sheets are excellent choices. And if you prefer crisp, hotel-style sheets, go with 100% cotton percale.

Ultimately, the best fabric for your summer bedsheets depends on your sleep preferences, skin sensitivity, and budget.
