The 20 Best Cooling Comforters For Hot Sleepers, Tested By PureWow Editors

With a 4.8-star rating and thousands of glowing customer reviews, it makes sense why people are coveting this comforter. The hype lies in its lab-tested, Evercool performance fabric, which absorbs and transfers heat 10-times faster than cotton (per the brand). The fabric is constructed with a fully drawn yarn technique that mimics silk—making it smooth and soft to the touch—and the ultra-thin fibers produce a non-stick sleeping environment that’ll keep you dry all night long. “The fabric is like nothing I've ever felt before—it’s like taking a dip in a silky, cooling pool,” PureWow Assistant Editor Delia Curtis says. “Somehow, it combines a satiny feel with the stretch of a jersey knit—all without heat-trapping properties. It’s buttery soft and moisture-wicking at the same time.”

Speaking of moisture-wicking properties: “It’s definitely helped with night sweats. I slept most nights with the window open, and this comforter only made me sweat on the nights I forgot to open the window. … The fabric dries very quickly—super absorbent—and allows me to fall right back to sleep if I do end up sweating.” As for durability? “I washed it on a normal cycle in cool water with the Dedcool X OUAI Melrose Place detergent and dried on a normal cycle…any major stains that were there before came right out,” Curtis adds.

We all know the famous Casper mattress, and now it’s time to get to know the brand’s humidity-fighting duvet. First, it’s constructed with layers of Merino wool to help wick away moisture, block humidity and regulate temperature throughout the night. “The merino wool was such a smart addition as it’s designed to wick away sweat—and I have terrible night sweats. Ever since I’ve been sleeping with this comforter, I haven’t woken up in a puddle of wet fabric. (Seriously!) It’s also incredibly thin and nothing like my usual fluffy comforters, so I’m sure that helped my body’s temp stay regulated,” says PureWow Associate Editor Stephanie Meraz.  

Beyond that, it also has a 100 percent cotton shell that not only makes it feel cool at the surface but also prevents the ethically sourced down fill from shifting or deflating over time. According to Meraz, this is what she loved most about the feel: “The comforter is far thinner than your average fluffy comforter, and it has these small sewn-in chambers everywhere that prevent the down filling from unevenly spreading…basically, this means I don’t have to fluff my comforter all the time just to get the filling from the bottom back up to the top. It’s all evenly distributed in its place and will never move. SUCH a game changer.”

If NASA approves of this comforter’s temperature-regulating Outlast technology, it’s probably safe to say you will, too. The 100 percent cotton cover gives the blanket its breathability, while the ClimaDry fiberfill helps wick away moisture, so you stay sweat-free while you sleep. What’s more, it has a more substantial feel than most cooling comforters: “When I hear ‘cooling comforter,’ I think of something thin and flat. This one, however, has a silky, jersey-like material that feels wonderfully plush and incredibly soft,” Curtis reports. “I loved the feeling of the cooling fabric. It definitely kept me from feeling overheated, and it was very absorbent!” 

To that end, they add: “The comforter was still a bit damp when trying to fall back asleep from night sweats. Yet, while the comforter retained a bit of a sweat smell over the course of two weeks, it completely came out in the wash. It definitely felt fluffy post-wash as well.” It’s also worth mentioning her warning on sweat resistance: “I do think that the comforter was cooling, but I did notice it wasn't as moisture-wicking as the Rest comforter I tried. I also found the fabric to be a bit slippery, like I was sliding around the bed.”

Speaking of soft and temperature-regulating picks, this airy comforter is made from plant-based materials, so it’s naturally ventilating and breathable. It has a 300-thread count sateen-weave with a Tencel lyocell fiber fill, aka a heat-fighting form of eucalyptus with open cells that allow for hot air to escape. “I don’t know if it’s a placebo effect, but I'm sleeping so much cooler with this comforter than I did before. (I even tested this theory on my other comforter, and no, I think this one is really making a difference!) I'm not waking up in the middle of the night feeling super hot. I still open my windows, but I'm not relying on my AC anymore to keep me cool,” says PureWow Associate Editor Chelsea Candelario.

As for the feel? “It's SO soft. It reminds me of a five-star hotel comforter and makes me want to lay in bed all day. It's made of TENCEL eucalyptus lyocell, so it's very lightweight and breathable. I can wrap it around myself without feeling like I'm being suffocated by heat,” she adds. Her only gripe? “It only comes in white! I would love it if it had more color variety to match my bedroom. I'm also more fearful of spilling on the comforter or causing a stain. Still, I appreciated that it's machine washable—I used Tide Pods to wash [it], and it was still soft and comfy to sleep with out of the dryer.”

While Brooklinen’s down comforter is available in three weights—including All-season, Ultra-warm and Lightweight—the latter’s 650-fill-power of duck down provides that Goldilocks loft; not too thin and not too thick. Rachel Bowie, senior director of special projects & royals at PureWow, loved this factor because it feels breezy and breathable while still being plush enough to curl up with: “The weight of the fabric made a huge difference with temperature regulation. I think it helps that the fill is so evenly distributed—it really has an airy, cloud-like effect so it's warm, but not heavy, which helps you stay cool.”

The down clusters and feathers are also evenly distributed in an ultra-soft, 400-thread-count cotton sateen shell, which offers a crisp outer finish that can help diffuse night sweats: “I have been wearing it with long sleeve PJs and still am not waking up with any sweats, which is my typical, nor am I peeling it off mid-night. It has the feel of an added layer, but doesn't lead to overheating,” Bowie says. Just remember that it’s dry-clean only, so you’ll definitely want to pair this guy with a machine-washable duvet cover for an extra barrier against spills and stains.

Made with an exclusive, plant-based CleanBamboo fabric shell with bamboo fiber filling, this comforter feels degrees cooler than cotton—and it’s a boon for hot flash sufferers and sleepers who tend to get overheated. You can also choose from two fill powers, including summer (200gsm) or winter (400gsm), so you know it’s suited for cooling in the summer and warmth in the winter. “It's not your standard big, fluffy comforter. The summer weight is thin, light and airy, while somehow being cool to the touch. I think the materials plus the relative thickness help contribute to a max cooling effect,” PureWow Executive Managing Editor Catrina Yohay says.

Cooling aside, it’s also pet-owner-approved: “I have a dog who loves to dig and has snagged many a comforter in the past, but after a few weeks, this one is holding up fine (no visible stitching for him to pull on). I have noticed a few stains here and there—probably from the dog—but those are easily spot-cleaned.” To that end, her biggest bummer was that it’s dry clean only. “To help preserve it [and] keep it clean, you could treat it as a duvet insert, since it has the hooks sewn in on the corners. I don't own a cover though, so we treated this like a standard comforter… Still, is it a comforter? Is it a duvet insert? Is it both? I don’t know—if I bought this expecting a comforter as it's marketed online, I probably would have been annoyed [and] returned it. Still, the functionality is great: It's cooling and comfortable and perfect for summer and/or hot sleepers,” Yohay summarizes.

With a Eucalyptus-fiber construction that’s naturally cooling, this comforter is uniquely hypoallergenic, so it’s resistant to dust, mite, and mold (so you can sleep without the sniffles). The materials are naturally super breathable, according to the brand, where its antibacterial properties are 1). great for sensitive skin, and 2). cool, soft and moisture-wicking by design. Plus, this comforter also features a silver ion, anti-microbial treatment, which slows the spread of microorganisms like bacteria and fungi.

“It's super light, and at first, I was afraid that I would be cold (because I run cold in the winter). However, I was curious because I sleep near the heating vent in my apartment, so I can get super warm/sweaty in the middle of the night. To my surprise and delight, I was always cozy but woke up less often overheating when the heater was on,” PureWow Associate SEO Editor Marissa Wu says. “I put a duvet cover on it. But before I did, the material was smooth and felt refreshing to the touch. Kind of slippery/slick—it was always cool when I tucked myself into bed at night. Plus, even though I did wake up a couple of times due to overheating, I was never sweaty under it.”

Perhaps the most customizable blanket on the market, this option from Sleep Number has temperature balancing, 37.5® Technology that continuously adapts to keep you cool. While the cover features 300-thread-count cotton, the fill has a blend of 60 percent polyester and 37.5 polyester technology, which attracts and removes moisture to resist humidity buildup. Even better? It lasts the life of the product, so it won’t wash out or wear out after time. PureWow Editorial Assistant Courtney Mason says: “I sometimes sweat in my sleep, but not to the point where I’d feel on the surface of my bedding. With this comforter, however, I noticed that I rarely sweat.” 

She also adds: “This is thinner than your average comforter; not too thick. The fabric is also somewhat thin with light stuffing, so it feels incredibly breathable. Honestly compares to an elevated blanket.” As for durability, Mason says, “I have two dogs who managed to stain the comforter almost immediately after I received it. I've washed it a few times already with baking soda and the stains have come right out…I am noticing a couple loose threads around the perimeter of the comforter, though.”

Quilts often make for a great all-season option—and this one in particular was designed with breathability in mind: “It doesn't feel heavy at all and its breathability is great for the warmer months—as someone who runs hot, this was excellent for air ventilation during the night,” says Phil Mutz, PureWow’s VP of News and Entertainment. This is thanks to the brand’s proprietary cotton-viscose blend, which is woven into a lightweight gauze for warmth without the bulk. “The quilt is soft to the touch and feels great on my skin. More importantly, the airflow definitely keeps me from getting too warm during the night.”

Not only that, but it looks good too: “The look is simple. If, like me, you prefer a minimalist, clean vibe to your bedding, the white option is for you…it features a simple pattern, giving it some depth and texture without looking busy,” Mutz says. Plus, if you’re worried about how the white will hold up in the wash, he backs: “The blanket didn't lose any of its comfortability or breathability after washing—and the color stays bright over time (just make sure to wash with other whites using a gentle cycle).”

Constructed with three-ply gauze fabrication and 100 percent long-staple Turkish cotton, this overstuffed quilt is an obvious must-have if you’re on the hunt for something light and airy (and oh-so-chic). Katherine Gillen, PureWow's senior food editor, says: “The poly batting fill makes the whole blanket feel very fluffy. It’s extremely soft, like a piece that's achieved the perfect amount of wearing in over the years (but right out of the box).” Aside from it feeling deliciously smooth on the skin, Gillen also says it’s a great summer option if you're trading out a down duvet: “It doesn't trap you in a sweaty mess like a synthetic fabric would, yet it's still surprisingly warm, thanks to the fill.”  To that end, it’s a middle ground between a regular quilt and a comforter, and it isn’t as wrinkle-prone as linen.

Still, while it came out of the dryer looking brand new, Gillen says you should be cautious with its delicate threads: “The gauze material is very prone to snagging and you have to be conscious of that when washing and for general use. (For example, I wear a permanent bracelet that always snags on this type of material, and I have to be really careful with it).” Overall, she summarizes: “I’m recommending this to my friends for summer because it's high quality, and the organic modern color palette is beautiful. The only caveat is that it's still pretty warm. If you’re a really hot sleeper, it won't be the most cooling option.” (See: number five on this list.)

The HydroCool ultra-plush temperature-regulating duvet is about as luxe as it gets. Both extra-fluffy and moisture-wicking, you’ll feel like you’re drifting off to sleep at a five-star hotel, wrapped in a 100 percent cotton-filled down-alternative cocoon with 300-thread count damask stripes. One reviewer writes: “The comforter features moisture-wicking fibers to keep you cool and dry while you sleep. Even in warmer weather or when I had the heat cranked up, I never felt hot or stuffy underneath it. Using baffle box construction, the blanket's filling remains evenly distributed and provides all-over warmth throughout the night.” Of course, with a blanket like this, you’ll have to pay standard shipping and return fees, but if it’s anything short of what you’ve always wanted, you’ll have 30 days to send it back.

Here, another gauzy, lightweight option that reviewers are loving. Muslin’s 365 blanket was intentionally designed for hot sleepers and those who suffer from night sweats, where its temperature-regulating, Muslin cotton features an 8-pound weight that can conform to your body—without trapping body heat. Per the brand, this guy was intended to be used "European Style," where it’s hefty enough to use on its own (without an extra blanket or quilt) while still offering maximum breathability. “I have gone through SO much bedding trying to keep myself cool and my husband warm. He crawled into bed the first night and immediately said he loved the warmth—and I loved that it didn’t make me hot,” one reviewer writes. Beyond that, many reviewers applaud its durability and oversized fit, where one person writes: “Being a huge king blanket (120 inches by 120 inches) it is very large and there’s plenty coverage for two people…it also comes out perfectly [from the dryer] and is still very soft with no shrinkage.”

What does sleeping on the Eucalypso Dream Comforter feel like? “Like you're floating on a big cozy marshmallow, being cocooned by airy wisps of cloud,” according to the brand. Mainly, this has to do with its 100 percent Tencel lyocell fibers (a fancy brand name for eucalyptus), which is silky soft on the skin—and ideal for anyone who’s allergy- and breakout-prone. Plus, it’s naturally cool to the touch and moisture wicking, where it’s finished in a special DreamWeave Technology that’s designed to be uniquely light, airy, and breathable. One reviewer raves: “I love, love, love [this] comforter…Not only is it wonderfully soft, but [it prevents from] disgusting sweat! I get very hot in my sleep, where sometimes, it even wakes me up. With [this] comforter, I slept straight through!”

Another reviewer writes, “I live in Texas where the weather tends to be bipolar. I’ll get night sweats but I’ll also get cold. [This comforter] has helped me stay dry [and] it feels super soft and silky against my skin.” However, it’s worth noting that they also mention: “The only reason I’m taking one star [off] is because I still get cold through the night. I do wish it was a bit more fluffy; it’s a bit thin, but I assume that’s what helps regulate your temperature.”

Two-sided comfort is the level of cozy you deserve and exactly what you’d get with this Bedsure warm and cooling comforter set. While one side of this 100 percent microfiber comforter is cooling and breathable, the other is warm and soft. “I am a person who always needs a heavier blanket when I sleep, even in the summer months. This allows me to sleep comfortably with the cooling side, not too satiny slick, but just enough smoothness to offer the cooling effect,” one Amazon customer writes. Reviewers also share how the pillowcases (yes, this is a full set) are a great addition: “The shams have a nice large fold-over which hugs the pillow and prevents pillow from showing,” one person adds.

As far as sustainability goes, you’ll be hard-pressed to find something more eco-friendly—not to mention comfortable—than this comforter by Avocado. Awarded the Greenguard Gold seal of acceptance by UL Environment (which few products qualify for), this comforter is rigorously tested for chemical exposure and pollutants (such as VOCs), formaldehyde and phthalates. It’s filled with GOLS-certified cotton percale (aka the best cooling cotton) and it’s cased with alpaca fibers that are renowned for supreme breathability, moisture-wicking, and thermoregulating properties. “I am very happy with [this] lightweight, organic cotton cover. It feels great, and the quality is high… The alpaca [fibers] feels just right, and so far, I’ve been cozy on cool nights (with temperatures between 65 and 70 degrees),” writes one reviewer. That said, they also warn: “In the beginning, there was a bit of wooly smell (that I did not find bothersome), and it’s not noticeable to me [at all] now.”

This trendy, year-round comforter can be used on its own (it's attractive enough, in blue, white or undyed colorways) or layered with a duvet cover for extra winter warmth. It’s made from crinkled percale fabric—which keeps you cool and comfy under its 360 GSM weight—and the GOTS-certified, shell fabric is naturally breathable and toxin free (aka great for anyone with allergies or sensitive skin). “[This comforter has] a nice thickness to give the bed a bit of ‘puff’ which I like. I thought it would be less insulating than down, because I live in the southeast, where it is very hot and humid. [Even when] we set our thermostat to 69 degrees, [I] still found this to be warm and [at times, almost] too heavy in the middle of the night…[still], if you live in a cooler climate, I think you’ll really enjoy this [stunning] comforter,” writes one reviewer. Bonus: The double-needle stitching keeps the all-cotton batting in place, and it's easy to store in a reusable cotton bag.

“Feeling stressed? Gravity’s cooling weighted blanket can theoretically increase serotonin and melatonin and decrease cortisol by using deep pressure stimulation to replicate the feeling of being held or hugged,” writes senior editor Dana Dickey. “The breathable moisture-wicking polyester cover does more than just wick away heat (and consequently, stress and anxiety); it actually allows air to move in and around your body. So you’ll get the pluses of having blanket weight, without the overheated-in-your-coat-in-a-crowded-elevator feeling.” It’s also worth mentioning that Gravity conducted a 2019 sleep study, where 72 percent of participants reported deeper, more restful sleep and 76 percent reported falling asleep faster when using the Gravity Blanket. And on top of its stress-reducing properties, it includes gridded stitching that ensures the glass beads remain uniformly distributed (and won’t shift if you toss and turn in your sleep).
