"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

While there’s no shame in sleeping hot—and inevitably waking up in sweat-soaked sheets—there’s no reason to settle for an uncomfortable sleep experience. So we found the best cooling comforters online that will do exactly what they say they’ll do: keep you cool. How do they do this, you may be wondering? Well, that depends on the specific comforter because each one elicits different technologies and materials that work to keep heat away from your body while you sleep. To better understand how these innovative products work, we chatted with the Vice President of Product Development at Casper, Russell Jelinek.

“Cooling comforters offer the same coziness and comfort as your average comforters but without the usual heat retention. They’re known to help improve sleep quality and reduce night sweats,” he says. So, if you tend to feel hot under the covers, worry not: there is a solution. In fact, there are 10. That’s right, we scoured the Internet for the best, most promising cooling comforters on offer. Did we mention that a few of our top picks are our very own comforters that we have and love? The rest of the products are some of the Internet’s most highly rated, so no matter which one you end up snagging for your sleep sanctuary, you will know all of the facts before buying. Plus, as the temperatures rise, now is the time to do some research to improve your summertime sleep.

Cloud Comforter

Hypoallergenic, machine washable, and sustainable, this all-season duvet insert is at the top of the list for a reason. Like Jelinek says, there is always something that actually makes a comforter cooling, and in the Buffy Cloud's case, it's the TENCEL eucalyptus lyocell fabric that absorbs moisture way faster than cotton. If you're wondering about the sustainable element, know that this is comprised of 50 recycled plastic bottles and is 100 percent GRS-certified and BPA-free. The fill is also made of recycled PET. Now, onto the cooling part: Our Assistant Editor Meghan Shouse says, "The Cloud from Buffy is a great cooling comforter for solo sleepers or couples who don't run too hot at night. It's extremely fluffy without feeling smothering and is a great cooling comforter for the winter months when you could still use a bit of coziness."

Breeze Comforter

Buffy's comforters all claim to be cooling, but this one is like sleeping with an air conditioner built right into the bed. It's temperature-regulating, naturally weighted, and exceptionally comfortable. In fact, in addition to the Cloud, Shouse also tested the Breeze, and she prefers the latter. "It is very breathable, to the point where I'm not sweating nearly as much in the night," she admits. "For me, the self-proclaimed hottest sleeper in the world, the Buffy Breeze comforter is the way to go." The shell is made of the same eucalyptus fabric as the previous pick, so it boasts similar moisture-wicking abilities, but this one is a little bit thinner, making it even cooler (and easier to store).

Like all Buffy products, this is highly sustainable. It's not just made with healthy, non-toxic materials; it's also fully biodegradable and compostable. The only downside? Unlike the Cloud, it's not machine washable.

Bamboo Comforter

Cozy Earth is famous for its sustainable practices, from the materials used to the manufacturing itself, so if you're looking for a cooling comforter that is eco-conscious, you can't go wrong with this one. It's also House Beautiful-approved, courtesy of Associate Editor Kelly Allen, who sleeps with the bamboo comforter in the warmer months. "The comforter itself is silky to the touch with an obvious sheen. Luckily, that softness didn’t translate to slipperiness. The fabric feels silky and soft, almost like thick silk sheets—but not too slippery that it’s annoying or falling off the bed," she says. "Hot sleepers are bound to love it all year round, while cold sleepers might enjoy it during warmer months." There's also an option to add some extra fill if you prefer your comforter on the fluffy side. P.S. Scoop up Cozy Earth's famous bamboo sheets while you're at it.

HydroCool Moisture-Wicking Duvet

Generally speaking, Pottery Barn isn't our typical destination for innovative bedding. A throw blanket? Sure. A coverlet? Of course. But a cooling comforter designed to draw heat away from the body using trademarked technologies? To anyone who may not know, Pottery Barn has an incredible selection of bedding that is highly competitive with bedding-only brands. Our favorite offering is the HydroCool duvet that effortlessly wicks away moisture while you sleep, providing cool comfort wrapped in hypoallergenic cotton. To really get into the nitty and gritty of how this product works, it's all about the fill, which is 60 percent regenerated polyester (made from 100 percent recycled plastic bottles) and 40 percent HydroCool performance polyester. This material is what actively pulls moisture away from the skin and forces it to evaporate on the surface of the fabric rather than on the body itself.

Evercool Cooling Comforter

There are a lot of bedding brands out there, and with such a densely saturated market, quality discrepancies are inevitable. In other words, some brands are better than others. Case in point: Rest, which may not be a household name (yet), but its products are some of the best on offer. The brand's most popular item is the cooling comforter, which comes in three additional colors. It's cooling in two ways: First, the cover itself literally feels chilled to the touch, courtesy of Rest's trademarked and lab-tested fabric, and second, the comforter is moisture-wicking.

If you're wondering how the cooling fabric works, peep the cute visual on the brand's site, which basically demonstrates how heat transfers. It's the same thermal conductivity that happens when you drop ice in hot coffee: the ice actually draws heat out of the coffee and infuses it into itself, which is why ice melts. In Rest's case, you are the coffee and the comforter is the ice. (No, it won't melt!) One reviewer said, "What a fantastic blanket. Soothingly cool and so smooth against the skin, this blanket is a dream come true. I am sleeping much better and deeper now that I am not feeling like a human furnace."

Snug Cooling Comforter

Sunday Citizen has dominated the luxury bedding space since its inception in 2018, and since the brand's launch, it's been coming out with incredible product after incredible product. One such item is the Snug cooling comforter, which features Sunday Citizen's innovative Tones of Cool technology that continually absorbs and releases heat (away from your body) to keep you at the perfect temperature all night long.

Not to mention, the Snug's all-in-one design totally eliminates some potentially unnecessary layers that can make you warmer, including the duvet, duvet cover, and top sheet. Lastly, the whole thing is wrapped in bamboo viscose fabric, which is naturally breathable. One reviewer said, "The comforters from Sunday Citizen are perfect for sleeping. I have both the Snug and now the Snug Cooling comforter. Both are great."

Comforter Duvet

For under $30, you can enjoy sweet, sweatless dreams in bed all year round. With over 90,000 five-star reviews, this Amazon bedding favorite is celebrated for its durability and light weight. While it isn't as advanced as some of the products on this list (moisture-wicking technologies aren't included), it is a worthy product investment that won't break the bank. And, if you're on a budget, nothing is better than that. Plus, if you're not in the market for a duvet cover, snag this comforter in 15 colors and patterns. Back to the coolness of it, though: One customer said, "I'm a hot sleeper and also have a memory foam mattress, so I tend to wake up feeling like I’m overheating if I don’t have a lightweight duvet. I got this to replace my torn duvet and it has been perfect for my needs! I plan to use this all year long."

The Humidity Fighting Duvet

Don't let the wool fool you—merino wool is actually the key to naturally sleeping cool and wicking away moisture. "Casper’s Humidity Fighting Duvet is a down comforter designed for those hot summer nights as it has a layer of merino wool to help wick away that moisture as you sleep, preventing you from overheating," Jelinek explains. If you're looking at the word "down" and thinking you'll still be warm, know that this beauty comes in two weights, full and light. One happy reviewer said, "We are loving our cozy new duvet. No more night sweats. It's also a good weight. All in all, we are very happy with our purchase!"

AiryWeight Eucalyptus Comforter

If your allergies arrive with a swift vengeance each year, this hypoallergenic comforter is for you (and your already puffy eyes). The eucalyptus fibers in Sijo's comforter are naturally resistant to dust, mites, and mold. You'll hit snooze daily to admire the silky, cool-to-touch outer layer and fluffy fill too. So what makes this so chill? The TENCEL Lyocell, which is made from the pulp of FSC- and PEFC-certified eucalyptus wood. By nature, it's cool, soft, and moisture-wicking. What's more, it's also bacteria-resistant and anti-microbial. "Incredible comforter for hot sleepers! I love that the comforter is so fluffy yet I don’t overheat and sweat at night. Bamboo comforters for the win," one reviewer said.

What to Look for When Buying a Cooling Comforter

Investing in a cooling comforter is all about focusing on the fill and fabric—if you're ignoring the materials, you might end up with a comforter that causes you to sweat twice as badly. A high-quality performance cooling comforter should be moisture-wicking, breathable, and regulate your temperature through the night. "Customers should look for breathable thermoregulating fabrics and heat-conducting technology in the comforter. The more effective these materials and tech are, the more satisfied you'll be with your sleep," Jelinek adds.

Fill: The lighter weight of the comforter, the less likely you are to sweat at night. Heavy comforters block airflow and keep the heat around your body. Search for a fill (marked as GSM) lower than 300. You can look for a down fill (luxurious) or synthetic depending on your allergies, budget, and insulation you're looking for.

Material: Wool, bamboo, down alternative, lyocell, Tencel, and linen are words you should keep an eye out for while shopping. These fabrics either naturally provide cooling properties or are blended to create an airy, moisture-wicking sleep experience.

What Is the Best Cooling Comforter for Hot Sleepers?

As you may expect, a cooling comforter is the best way to keep hot sleepers comfortable and sweat-free. Contrary to common belief, a cooling comforter isn't just a regular comforter, but thinner. It can be plush and fluffy and still keep you cool. How, you may ask? "Innovative technologies," says Jelinek. "The two most crucial elements that determine cooling are thermoregulating fabrics and heat-conducting technologies." The first includes lightweight and breathable materials that work naturally to reduce heat by drawing moisture away from the body. The second element involves specific designs that allow heat to transfer from one place (you) to another (the outer cover of the comforter). "The blend of these technologies results in the cooling sensation you feel throughout the night," Jelinek says.

What Is the Best Material for a Cooling Comforter?

Luckily for anyone with specific needs (allergies, budget, or anything in between), you aren't exactly limited when it comes to materials that cool you off on a warm night. "The best thermoregulating fabrics are cotton, polyester, acrylic, wool, and TENCEL Lyocell," Jelinek says. "Comforters that combine these breathable fabrics, like in Casper’s Lightweight Humidity Fighting duvet, are especially effective at keeping temperatures cool." If you’re looking for a more breathable structure, it's important to look for fabrics like these along with bamboo, cotton, silk, percale, and satin to name a few.

"There’s no clear-cut answer regarding which fabrics offer the most cooling benefits since many types of fabrics, thread counts, and weaves provide airflow and absorbency in different ways, but you will find that some materials are naturally more breathable than others" Jelinek adds. "Comforters that combine these breathable fabrics are especially effective at keeping temperatures cool."

Do Down Comforters Keep You Cool in the Summer?

When it comes to down comforters, there are different types: all-season, cold, and warm. Cold weather down comforters tend to be a bit fluffier and voluminous and warm weather ones are often a lot thinner, but it's not exactly cooling. So if you sleep very hot and need something with cooling abilities, either buy a down comforter with specific technologies that keep you cool or skip the down and opt for a highly rated cooling comforter. "Certain down comforters are meant to keep you warm, but ultimately, it just depends on personal preference and how hot you get at night—especially during the summer," Jelinek says. "Casper’s Humidity Fighting duvet is a down comforter designed for those hot summer nights as it has a layer of merino wool to help wick away that moisture as you sleep, preventing you from overheating."
