What Is The Coolest Fabric For Pillow Cases?

When it comes to keeping cool throughout the night, the fabric of your pillowcase plays a significant role. Breathable materials that wick away moisture and promote airflow are ideal. Currently, bamboo-derived fabrics, such as bamboo rayon or lyocell, are some of the coolest fabrics for pillowcases. They are not only soft and comfortable but also have excellent moisture-wicking properties and are environmentally friendly. In addition to bamboo, other fabrics such as cotton, particularly organic or Egyptian cotton, linen, and silk are also known for their cooling effects and are worthy choices for those looking to stay cool at night.

Understanding the Importance of Sleep Temperature

Before diving into fabrics, it’s crucial to understand why pillowcase material matters for sleep temperature. The body’s core temperature naturally drops as we head towards slumber, signaling the body it’s time to rest. However, if our sleep environment, including our pillow, retains too much heat, it can disrupt this natural temperature regulation, leading to discomfort and sleep disturbances.

Heat Retention and Breathability

Pillowcases that retain heat can lead to overheating and sweating, whereas breathable fabrics allow for air circulation, carrying away excess heat and moisture. This is why fabric choice for pillowcases is not just a matter of texture and aesthetics but also a functional decision that can impact sleep quality.

Bamboo: A Top Contender for Coolness

Bamboo fabric has surged in popularity due to its cooling properties, sustainability, and soft feel. Let’s explore why bamboo stands out:

Eco-Friendly and Sustainable

Bamboo is a quickly renewable resource that requires less water than cotton and no pesticides, making it an eco-conscious choice.

Moisture Wicking

Bamboo has natural moisture-wicking properties, which means it can draw sweat away from the skin, allowing it to evaporate quickly and keep the sleeper cool and dry.

Thermal Regulating

Fabrics like bamboo rayon and lyocell—both derived from bamboo—are great at regulating temperature, staying cool in summer and warm in winter.


For those with sensitive skin, bamboo is naturally hypoallergenic, resisting dust mites and mold, contributing to a cleaner sleep surface.

Cotton: A Classic Choice

While bamboo is a fantastic option, cotton remains a timeless favorite for its accessibility and variety.

Egyptian Cotton

Egyptian cotton is lauded for its long fibers, creating a fabric that is lightweight, soft, and highly breathable. It is considered one of the best cotton types for those who sleep hot.

Organic Cotton

Organic cotton is cultivated without harmful chemicals and pesticides. Its natural properties allow for air circulation and durability, making it a cool and green option as well.

Percale Weave

The weave of the fabric also contributes to its coolness. A percale weave, often found in cotton bedding, is especially breathable with a crisp feel that stays cool against the skin.

Linen: The Inherently Airy Fabric

Linen is another natural fabric known for its relaxed, breathable nature.

Highly Breathable

The structure of linen fibers allows for exceptional airflow, making it exceedingly breathable and perfect for warm sleepers.

Moisture Absorbent

Linen can absorb up to 20% of its weight in moisture before feeling damp, keeping you dry and cool throughout the night.

Linen is also one of the strongest natural fibers, so while it may be an investment, it’s one that could pay off with many years of cool, comfortable sleep.

Silk: Luxury that Keeps You Cool

Silk may be known for its luxurious feel, but it’s also a great choice for temperature regulation.

Smooth and Cool to the Touch

Silk is inherently cool to the touch, providing an immediate cool surface for your skin when you lay your head down.

Hypoallergenic and Smooth

Not only is silk hypoallergenic, but its smooth fibers can also be beneficial for skin and hair, reducing friction and preventing breakage and sleep creases.

Natural Temperature Regulation

Silk fibers are natural temperature regulators, helping maintain a comfortable body temperature throughout the night.

Microfiber: An Affordable Alternative

For those on a budget, microfiber is an option to consider.

Lightweight and Soft

High-quality microfiber can be soft and lightweight, though not as breathable as the natural options mentioned previously.

Wicks Moisture

Some microfiber options are designed to wick moisture away from the body, which can help keep sleepers cool.

Consider Thread Count

With any fabric choice, the thread count can impact breathability. Usually, a thread count between 200 and 400 is the sweet spot for coolness and softness without trapping too much heat.

What to Look For in a Cool Pillowcase

Besides the material and weave, other factors contribute to the cooling properties of pillowcases:

Pillowcase Fit

A pillowcase that fits snugly can reduce airflow. Make sure your pillowcase is not too tight around your pillow to allow for adequate ventilation.

Moisture-Wicking Technologies

Some fabrics come with advanced moisture-wicking technologies, which can further enhance their cooling capabilities.

Color and Dye

Light-colored fabrics tend to reflect more heat, staying cooler than their darker counterparts.

Care and Maintenance

Proper care can maintain the cooling properties of a pillowcase. Follow the manufacturer’s instructions for washing and drying to keep the fabric in optimal condition.

Finishing Thoughts

Choosing the coolest fabric for pillowcases is ultimately about personal preferences and individual needs. Bamboo, cotton (especially Egyptian and organic with a percale weave), linen, and silk stand out as top choices for those who sleep hot. Microfiber can also be a consideration for budget-conscious shoppers. Evaluate factors such as breathability, moisture-wicking properties, hypoallergenic traits, and environmental impact when making your decision. Remember, investing in the right cooling pillowcase can contribute to a better night’s sleep, promoting overall well-being and comfort. With mindful selection, your nights can be transformed into a cool and restful slumber sanctuary.
