A cooling blanket might be the perfect bed cover if you sleep hot or get night sweats. "Look for lightweight (preferably natural) fabrics with relatively low thread counts to ensure adequate airflow," says Logan Foley, a certified sleep science coach and managing editor at SleepFoundation.org.
Using Foley's expert insight into temperature-regulating bedding, we researched various styles and textile technologies that promise a comfy nighttime temp.
These are the best cooling blankets currently on the market.
Pottery Barn SleepSmart Temperature-Regulating Basketweave Blanket
Special "37.5® Technology"
Light and breathable
Only one color
Our favorite cooling blanket is Pottery Barn's exclusive SleepSmart Blanket, a soft basketweave design with temperature-regulating abilities. It's made of 80 percent cotton, a naturally breathable and moisture-wicking material, and 20 percent performance polyester with 37.5® Technology.
The latter is a cutting-edge textile that promises to keep your body at an ideal temperature while you doze—37.5 Celcius, to be exact (or 99.5 F). Not only that, but it keeps your skin at a relative humidity of 37.5 percent by drawing sweat away and vaporizing it. According to Pottery Barn, the thermoregulating technology also traps energy to keep you cozy when your body temp cools off.
Available in two sizes (full/queen and king/California king), this cooling blanket is notably light, with a weight of 370 GSM (grams per square meter). Like most comparable products, it's somewhat pricey, and we wish it came in more colors. However, the white is versatile, and we appreciate the machine-washable, dryer-friendly design.

Material: Cotton, 37.5 performance polyester | Sizes: Full/queen, king/Cal. king | Care: Machine wash, tumble dry
Dangtop Bamboo Cooling Blanket
Requires line drying out of sun
Though most temperature-regulating blankets are priced pretty steep, the Dangtop Bamboo Cooling Blanket is an affordable option woven from 100 percent bamboo fibers. The renewable material is not only eco-friendly but also inherently breathable and naturally moisture-wicking with a cool-to-the-touch feel. Bamboo is also exceptionally soft.
This blanket comes in three sizes (twin, queen, and king) and several colors ranging from charcoal to white to lavender. It's machine washable too, but it's best to lay it flat or dry it outdoors on a clothesline.

Material: Bamboo fiber | Sizes: Twin, queen, king | Care: Machine wash, line dry
Luna Cooling Bamboo Weighted Blanket
Smaller than typical bedding sizes
King option is only shared size
If you're interested in a weighted design, look no further than the Luna Cooling Bamboo Weighted Blanket. This machine-washable blanket comes in five sizes, though they're smaller than the typical blanket sizes most manufacturers use and all but the king option are individual-use. Depending on your choice, this blanket is available in numerous weights, ranging from 10 to 30 pounds, to accommodate sleepers weighing between 100 and 300 pounds. A substantially smaller kid version weighs 5 pounds for children closer to the 50-pound range.
It's filled with evenly distributed polyester and glass beads and has a bamboo-derived lyocell shell. The cool-to-the-touch fabric is naturally breathable, temperature-regulating, moisture-wicking, and antimicrobial, meaning it won't harbor odor-causing bacteria. This weighted blanket is also Oeko-Tex certified, so you can rest assured it's free of over 100 potentially harmful substances.

Material: Lyocell bamboo, polyester/glass beads | Sizes: Kid, twin, full, queen, king | Care: Machine wash, tumble or line dry
Luxome Lightweight Blanket
Thin, quilted design
For something a bit lighter, we recommend the Luxome Lightweight Blanket. This soft, quilted bed cover is much thinner than a traditional duvet, offering a lightweight layer that keeps you comfortable year-round. This blanket uses bamboo-derived viscose, a thermoregulating fabric with a natural ability to warm or cool you, depending on what your body needs.
While our only significant complaint is the expensive price tag, this breathable blanket comes in two sizes (full/queen and king/California king) that are oversized for neat mattress tucking and five versatile colors. You can use it as is or with a duvet cover, and when it needs cleaning, toss it in your washer and tumble dry it on low heat.

Material: Bamboo-derived viscose | Sizes: Full/queen, king/Cal. king | Care: Machine wash, tumble dry
Best with 37.5® Technology
Sleep Number True Temp Blanket
Might not be as soft as alternatives
Sleep Number's True Temp Blanket calls on 37.5® Technology to regulate your body temperature. This performance polyester infused with volcanic minerals continuously draws moisture away from your skin and vaporizes it to keep you cool throughout the night. And if you ever get too cold, the technology adjusts to trap energy instead, effectively warming you up.
The shell is 20 percent 37.5® polyester and 80 percent cotton, so it also has natural breathability and sweat-wicking abilities. This cooling blanket is available in two sizes and five neutral colors that are machine-washable and dryer-friendly. The price is somewhat steep, though it's about average for a high-quality duvet. Depending on your preferences, the material could also feel less cozy than other alternatives.

Material: Cotton, 37.5® performance polyester, poly fill | Sizes: Queen, king | Care: Machine wash, tumble dry
Vesta Washable Cooling Silk Blanket
Vesta's Washable Cooling Sink Blanket's filling uses premium silk fibers from mulberry worms that exist freely in the forest. In addition to being exceptionally lightweight, the material is inherently airy with moisture-wicking properties, making it ideal for hot sleepers and those who suffer from night sweats.
The shell is Tencel lyocell, which also boasts natural breathability and temperature-regulating abilities. While this machine-washable bed cover is incredibly smooth and soft, it's undoubtedly expensive. It also calls for line-drying only but might be worth splurging for a comfortable night's sleep.

Material: Tencel lyocell, silk | Sizes: Full/queen, king/Cal. king | Care: Machine wash, line dry
Cozy Earth Cloud Knit Throw
Cozy Earth makes our favorite cooling throw. The Cloud Knit Throw is woven from 100 percent bamboo-derived viscose, a super-soft and naturally airy material. It keeps you slightly cooler than cotton, making it a top choice for those who run hot.
This blanket measures 60 x 50 inches (standard throw size). While it comes in only two colors (white and ivory), it's undeniably versatile. Thanks to an enhanced weave structure, the durable knit material is resistant to pilling. You can also toss it in your washing machine and tumble dry it on low heat without worrying about the yarns coming loose.

Bearaby Cotton Napper
Oeko-Tex and Fair Trade certified
Seven chic colors
We also like this chunky-knit option from Bearaby. The Tree Napper weave uses 48 percent Tencel lyocell, 47 percent organic cotton, and 5 percent spandex. These materials offer thermoregulation while you sleep, cooling you down when you're hot and insulating your body when you have chills.
This versatile blanket comes in several chic colors, ranging from emerald to ochre to mauve, and three sizes weighing 15, 20, and 25 pounds. It can be used as a bed cover, a living room throw blanket, or a snuggle companion any time you're in the mood for weighted comfort without the heat. The Tree Napper is expensive, but we like that it's Oeko-Tex and Fair Trade certified, ensuring it's free of harmful chemicals and produced by ethically treated workers.
Price at time of publish: $269
Our top choice is Pottery Barn's SleepSmart 37.5 Basketweave Blanket because of its temperature-regulating technology, sweat-wicking abilities, and machine-washable, dryer-friendly design. On a budget? You can't go wrong with the naturally thermoregulating and exceptionally soft Dangtop Bamboo Cooling Blanket.
What to Look For in a Cooling Blanket
Logan Foley, a certified sleep science coach and managing editor at SleepFoundation.org, recommends natural, lightweight fabrics, such as cotton, bamboo, silk, linen, and Tencel lyocell, all of which are naturally breathable with moisture-wicking properties.
In addition to natural fibers, some cooling blankets feature 37.5® performance polyester. This material helps keep your body at an optimal temperature while you sleep while pulling sweat away from your skin.
Some cooling blankets are weighted, with options ranging from about 10 to 25 pounds. Research suggests that gentle pressure can be emotionally comforting, similar to a hug, with potential benefits for those suffering from anxiety or insomnia. While the added weight might seem like it would heat you up, some temperature-regulating designs do an excellent job cooling you off.
Lastly, you'll want to consider the design. There are various types of cooling blankets, including throws, quilts, and comforters. Some temperature-regulating blankets can go inside a duvet cover, in which case the design may not matter as much. But if you plan to use it as is, think about where you'll place it and whether the color, finish, and texture will complement your existing decor.
What is a cooling blanket?
A cooling blanket is a type of blanket made from materials that help regulate your body temperature to prevent you from overheating. In many cases, it can also help wick away sweat while ensuring breathability.
However, Foley says textiles aren't actively cooling per se. "Bedding materials can be temperature-neutral, meaning they won't make you hotter by trapping heat," she explains.
What types of materials are cooling?
"The best bedding materials for people who sleep hot are made from linen, bamboo, cotton, or silk," says Foley. She explains that these natural temperature-neutral (also known as thermoregulating) fabrics won't trap or absorb heat like most synthetic textiles.
As mentioned, some cooling blankets feature temperature-regulating technology by way of performance fabrics like 37.5® polyester. These materials draw heat and moisture away from your body when you overheat and offer insulation if you get too cold.
Can you use a cooling blanket year-round?
It depends on the specific blanket, where you live, and your personal preferences. That said, many cooling blankets are perfectly suitable for year-round use. Why? In addition to preventing you from overheating, the temperature-regulating technology can adjust to keep you warm when your body cools off.
