While summer brings the promise of poolside cocktails and backyard BBQs, it also brings the undesirable: drenched sheets. Indeed, if you’re a sweaty sleeper, a cooling comforter (and mattress) is as essential to the warmer months as ice pops and pool floats—and we’re here with a list of 19 that won’t disappoint. After hours of scouring the internet for the top-reviewed products, we’ve found the absolute best cooling comforters.

From the NASA-approved cooling technology used in the Slumber Cloud lightweight comforter (from $159) to the breathability of the Buffy breeze (from $140), these picks will keep you from waking up at 3 a.m., drenched in sweat. So here’s looking at you, fellow hot sleepers, because it’s time to stop those night sweats from getting progressively worse as the temperature climbs.

How We Chose the Best Cooling Comforters

After sifting through thousands of customer reviews, we vetted each cooling comforter based on whether it used temperature-regulating technology, had breathable materials, used a lightweight weave (specifically for quilts) and whether they had a durable construction that resists piling or fading over time.

Best Comforter Overall

1. Slumber Cloud Lightweight Comforter

What We Like

  • outlast technology stores and releases heat based on your body temperature
  • hypoallergenic
  • 180-night warranty

What We Don't Like

  • one color option
  • may be too thin to fill a duvet cover

Slumber Cloud

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. The real kicker, however, is its unprecedented temperature regulation: “Outlast technology is proactive, not reactive. As your body temperature increases during sleep, [the comforter] stores that heat to keep you cool, and then releases it as you cool down—keeping you feeling ‘just right,’” per the brand.

One reviewer backs this up, writing: “This comforter is perfect for both hot and chilly sleepers. It really does seem to adjust to both hot flashes, and chilly room temps. During a frigid Christmas week blizzard, we were kept very comfortable under this duvet—despite our drafty house trying to keep up with sub-zero temps and gale force winds. Next week, when the temperature rose [by] 50 degrees, we were just as comfortable under this lightweight comforter. This one's a keeper!” Psst: The brand also offers free shipping on U.S. orders and free returns before the end of a 60-night trial (and 180-night warranty).

Fast Facts

  • Shell Material: 300 thread count cotton
  • Fill Material: ClimaDry by Outlast fiberfill
  • Care Instructions: machine-wash with a mild detergent in cold water on a delicate spin cycle. Dry on low heat or air dry.

Best Temperature Regulating Comforter

2. Casper Humidity-Fighting Duvet

What We Like

  • anti-humidity technology
  • RDS-certified
  • baffle-box construction keeps fill in place

What We Don't Like

  • low fill power
  • duvet cover not included in the price

Casper

We all know the famous Casper mattress, and now it’s time to get to know the brand’s humidity-fighting duvet. Take it from PureWow contributor Taylor Mead: “It made me feel like I was wrapped in a cloud. Its layer of Merino wool adds a cooling technology to help wick away moisture, block humidity and regulate temperature throughout the night. It also has a 100 percent cotton shell that remained crisp and cool, and it features an ethically sourced down filling (which is a major bonus, if you’re a tree-hugger like me). It also fluffed right back up after I sat on it, and the sewn pockets allow the down to remain in place—it remains perfectly feathered, no shifting or fluffing over time.

My only complaint, however, was that the lightweight option was not very lofty, and I was disappointed by how thin it was compared to the photos. Nevertheless, this comforter delivered on all of its cooling promises: It wicked away moisture like a pro and kept me sweat-free all night long.”

Fast Facts

  • Shell Material: 100 percent cotton
  • Fill Material: ethically sourced down 
  • Care Instructions: machine-wash cold on a gentle cycle. Tumble dry low.

Best Moisture-Wicking Comforter

3. Rest ‘Evercool’ Comforter

What We Like

  • moisture-wicking fabric
  • soft and silky to the touch
  • machine washable

What We Don't Like

  • material might feel slippery
  • tends to slide off the bed

Rest

With a 4.8-star rating and more than 1,000 positive 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.

One reviewer writes, “My wife was suffering nightly with severe night sweats and hot flashes due to a medical condition. We had tried everything, [but] she would wake up several times a night drenched and incredibly uncomfortable. Since we purchased this comforter, she can sleep through the night comfortably [and sweat free].” And they’re not the only one. “Before receiving this comforter, I would wake up dripping in sweat every morning, no matter how cold it was outside,” another reviewer shares. “Since I have been using the Rest comforter, I have woken up dry for the first time in years.” On top of that, however, the comforter is also reversible, and the fabric features anti-pilling and anti-snagging fabric (that’s also good at repelling pet hair).

Fast Facts

  • Shell Material: Evercool fabric
  • Fill Material: Sorona fill
  • Care Instructions: machine-wash on gentle. Tumble or hang dry. 

Most Breathable Comforter

4. The Buffy Breeze

What We Like

  • wave-stitch pattern helps keep materials in place
  • hypoallergenic
  • OEKO-TEX certified

What We Don't Like

  • thin feel
  • no temperature-regulating technology

Buffy

“If you’re looking for a lightweight duvet that works for every season, is eco-friendly and cozy AF—and won’t make you sweat in your sleep—the Buffy is it,” writes our tester in a PureWow100 review. “It’s made with 100 percent eucalyptus fill—so it doesn’t trap heat like polyester or down—and its [materials feature] cool to the touch eucalyptus [with a] fiber shell that’s temperature-regulating. All that to say: This blanket was made for down-blanket devotees who can’t give up that cozy feel...even in July.” Plus, the brand offers a seven-night trial, so you can sleep with it for a week before deciding to keep it. If you decide to return it after that trial, you have 30 days to initiate the free return for a full refund.

Fast Facts

  • Shell Material: tencel eucalyptus lyocell
  • Fill Material: tencel eucalyptus lyocell
  • Care Instructions: recommended dry clean only.

Best Bamboo Comforter

5. Cozy Earth Bamboo Comforter

What We Like

  • lightweight-yet-insulating
  • ultra-soft
  • hypoallergenic
  • enhanced to resist pilling

What We Don't Like

  • expensive
  • spot-clean only

Cozy Earth

Made from moisture-wicking viscose that's derived from bamboo, this comforter feels degrees cooler than cotton—and it’s a boon for hot flash sufferers and sleepers who tend to get overheated. “I highly recommend this product for warm sleepers, one reviewer writes. “It has the softest, [silky] material and best temperature control. It’s light [but] still provides a nice weight at night for added comfort and warmth on cooler nights. The seven-day trial period [also] helped confirm that I want to keep this product.” Plus, because wrapping yourself up burrito-style in a genuine down comforter can lead to pesky allergy symptoms, this one’s bamboo base is hypoallergenic and as a result, it does an exceptional job at keeping allergies at bay. Oh, and did we mention that the fabric feels ridiculously smooth on the skin and is enhanced to resist pilling?

Fast Facts

  • Shell Material: 100 percent viscose from bamboo
  • Fill Material: viscose from bamboo
  • Care Instructions: spot clean or dry clean only.

Best Eucalyptus Comforter

6. Eucalypso 'The Dream' Comforter

What We Like

  • dreamweave technology is designed to be light and breathable
  • prevents night sweats
  • ideal for anyone who’s allergy- and breakout-prone

What We Don't Like

  • no twin/twin XL size available
  • expensive
  • one color

Eucalypso

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.”

Fast Facts

  • Shell Material: 100 percent tencel lyocell eucalyptus
  • Fill Material: tencel lyocell eucalyptus
  • Care Instructions: machine-wash separately in cold water on gentle cycle and hang to dry.

Best Down Comforter

7. Brooklinen Lightweight Down Comforter

What We Like

  • three fill options
  • insulating without trapping heat
  • corner loops
  • baffle box construction keeps fill from shifting

What We Don't Like

  • not machine-washable
  • feathers may poke out 

Brooklinen

Yet another cooling number this editor loves? Brooklinen’s lightweight down comforter. While it’s 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. I loved this option because it felt breezy and breathable, while still being plush enough to look like it came straight out of a Nancy Meyers film. More importantly: The filling was simultaneously insulating and breathable and I was impressed by how warm it kept me without causing overheating. It’s also worth mentioning that the down clusters and feathers are evenly distributed in an ultra-soft, 400-thread-count cotton sateen shell, which offers a crisp outer finish that’s noticeably cool from the second it comes out of the box.

Fast Facts

  • Shell Material: cotton sateen shell
  • Fill Material: down cluster fill
  • Care Instructions: spot clean recommended. Dry clean if needed.

Best Down Alternative Comforter

8. Pottery Barn Hydrocool Down Alternative Duvet

What We Like

  • HydroCool technology with performance down
  • moisture-wicking
  • three fill powers

What We Don't Like

  • recommended duvet sold separately

pottery barn

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.

Fast Facts

  • Shell Material: 300 thread count cotton 
  • Fill Material: 60 percent regenerated polyester (made from recycled plastic bottles) and 40 percent HydroCool performance polyester
  • Care Instructions: machine-wash in cold water, gentle cycle.

Best Cotton Comforter

9. Parachute Organic Cloud Cotton Quilt

What We Like

  • gauzy and lightweight
  • beautifully constructed with Turkish cotton

What We Don't Like

  • better for summer months
  • prone to snagging

Paracute

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). “This is the best quilt I have ever bought! It's soft and cold, but heavy and warm—the perfect [balance] of all the things I need to get a good night's rest,” one reviewer writes, adding that it helped ward off bouts of insomnia. However, it’s worth noting a few reviewers mentioned snagging: “My only criticism is that it snags super easily…I got a piece of Velcro stuck on the quilt right after I purchased it, and it left a snag.” But that snag didn’t make them regret their purchase: “It's cozy and the right weight to use year-round—and it looks beautiful on our bed, I love that it is reversible…Overall I'm super happy with [the feel of this] and would definitely [buy it again].” On top of that, it’s gauzy, dream-like feel, it’s also machine washable and available in seven earth-toned colorways.

Fast Facts

  • Shell Material: 3-ply gauze made of organic cotton.
  • Fill Material: poly batting
  • Care Instructions: machine-washable.

Best Lightweight Comforter

10. Muslin 'The 365' Blanket

What We Like

  • doesn't trap heat
  • oversized fit with 8-pound weight
  • naturally temperature-regulating

What We Don't Like

  • might be too thin for those who live in cooler climates
  • more of a blanket than a comforter

Muslin Comfort

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.”

Fast Facts

  • Shell Material: pure muslin cotton
  • Fill Material: muslin cotton
  • Care Instructions: machine-washable.

Best Winter Comforter

11. Sunday Citizen Snug Comforter

What We Like

  • double-sided design
  • fluffy-yet moisture-wicking

What We Don't Like

  • not lightweight/has a thicker feel overall 
  • snug fabric is likely too hot for summer months

Sunday Citizen

High body temperatures mean sweat, and sweat has the unfortunate tendency to cause undesirable smells. Lovely, right? The good news is that this ultra-plushy comforter features an innovative two-sided design, with fluffy microfiber fabric on top and naturally cooling, hypoallergenic viscose from bamboo underneath. More importantly: It’s completely machine washable, so you can hit the hay in a fresh-smelling (reversible) blanket that’s interchangeable with the seasons. “Having a two-sided comforter is awesome,” writes one reviewer. “We use the bamboo side for summer and it’s sooo soft and cooling! [The other side] also makes me excited for winter, knowing I get to lay in [plushy] bed and snuggle up to a cozy, cuddly [microfiber].”

Fast Facts

  • Shell Material: microfiber on one side, viscose from bamboo on the other
  • Fill Material: GRS-certified recycled polyester
  • Care Instructions: wash in a high-capacity washing machine on low or no spin cycle. Once the cycle is finished, select the "Spin only" cycle on low. Tumble dry low.

Best Year-Round Comforter

12. Molecule Year-Round Comforter

What We Like

  • hefty feel
  • cooling technology
  • hypoallergenic
  • fibers absorb moisture

What We Don't Like

  • no lightweight option
  • one color
  • fill may not disperse throughout

Molecule

Made from cotton and Tencel with an eco-friendly filling designed to regulate moisture and heat, the Molecule's year-round comforter is another hypoallergenic option that can be used during any season—hot or cold. “As a middle-aged woman, I was on the hunt for [something] that would help with the side effects of menopause, night sweats and hot flashes. [This] comforter feels heavenly and has help me tremendously. It has the feel of a weighted blanket and makes me feel like my momma is hugging me. I feel like I’m sleeping in a fluffy, cool, heavenly cloud,” one reviewer writes. Add in free standard shipping and returns within 90 days, there’s really nothing to lose and many great nights’ sleep to gain. (Pro tip: Pair it with the brand’s AirTEC mattress topper for an even cooler sleep.)

Fast Facts

  • Shell Material: long-staple cotton 
  • Fill Material: poly-puff and tencel lyocell
  • Care Instructions: machine-wash in cold water, delicate cycle. Tumble dry low.

Best Comforter for Couples

13. Comma Eucalyptus Lyocell Comforter

What We Like

  • naturally hypoallergenic
  • antimicrobial
  • recycled materials
  • prevents night sweats

What We Don't Like

  • no twin/twin XL size available
  • may not be thick enough to use as an all-season option

Comma Home

Another comforter that’s versatile enough to meet your (and your partner’s) needs? This Eucalyptus number from Comma. It’s made from 100 percent eucalyptus lyocell, which is touted to be “softer than silk and cool to the touch,” per the brand, and its inside filling (which is made from recycled water bottles) is designed as a one-sheet, “so you won’t see excess fluff randomly bunching up in the corner.”

So, how does it hold up after a year? Here’s what one reviewer had to say: “It has minimal pilling, is relatively easy to wash and has held up [in the wash after] being used nightly. I run hot and get very uncomfortable in bed if the temperature is above 71 degrees. At that temp, I'm usually not using the comforter all the way up to my shoulders/chin, but I keep it across my legs. In the winter, this thing is absolutely perfect. I named this review ‘middle of the road’ because that's what I feel like it is: the comforter than meets both my needs as a hot sleeper and my girlfriend's needs who sleeps buried under the comforter wearing a hoodie and shorts in the July. Like [other reviewers] I agree that it is extremely soft and cushy, like being cuddled by a cloud!”

Fast Facts

  • Shell Material: 100 percent eucalyptus lyocell
  • Fill Material: recycled water bottles
  • Care Instructions: machine-wash on a gentle cycle. Use your dryer’s lowest setting.

Best Comforter Under $40

14. Linenspa Down Alternative Quilted Comforter

What We Like

  • lightweight, breathable fill
  • works as a duvet insert or stand-alone comforter

What We Don't Like

  • not durable

Linen Spa

Made from 100 percent polyester and a microfiber down alternative fill, the Linenspa all-season down alternative comforter is one of Amazon’s best-sellers with more than 26,000 five-star reviews. According to reviewers, this lightweight and hypoallergenic comforter gives the best of all worlds: light yet fluffy, while staying cool in the winter and warm (but not too much so) in the summer. Take it from one person, who writes: “I find [this comforter to be] fluffy and lightweight [with] a cozy warmth. I am using it in cool summer weather and it’s perfect, [where] I’m comfortable without any feeling of extra-weight…The weightlessness [is great for cooling] where the filling provides an enveloping warmth [that doesn’t overpower].” Plus, for under $40, with Prime delivery and free returns, you really can’t sleep on this deal.

Fast Facts

  • Shell Material: microfiber
  • Fill Material: 300 gsm down alternative 
  • Care Instructions: machine-wash on gentle cycle and air dry. (Or dry on a low heat setting.)

Best Weighted Comforter

15. Gravity Weighted Cooling Comforter

What We Like

  • three weights
  • stress-reducing properties
  • moisture-wicking fabric
  • removable cover

What We Don't Like

  • insert is hand-wash only

Gravity Blanket

“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).

Fast Facts

  • Shell Material: 100 percent lyocell from eucalyptus
  • Fill Material: glass beads
  • Care Instructions: cover is machine washable (wash in cold water, tumble dry on low). Inner weighted blanket is hand-wash-only and air dry.

Best Hypoallergenic Comforter

16. Sijo AiryWeight Comforter

What We Like

  • eco-friendly materials
  • naturally hypoallergenic
  • antimicrobial

What We Don't Like

  • dry-clean only
  • too thin for winter

Sijo Home

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.

“I am so glad I purchased the eucalyptus comforter. I have been sleeping better as my body temperature stays even and perfectly comfortable! It is soft like a dream. I also have allergies and asthma and I am breathing better at night with this wrapped around me," one reviewer writes. Another adds: “The snap ties are really well done too—there's no sliding around of the insert at all if you put on the cover using the inside-out method, attaching all the ties.”

Fast Facts

  • Shell Material: Tencel lyocell
  • Fill Material: Tencel lyocell
  • Care Instructions: dry-clean only.

Best Decorative Comforter

17. Coyuchi Diamond-Stitched Comforter

What We Like

  • cooling crinkled percale
  • double-needle diamond-shaped quilting holds the fill in place

What We Don't Like

  • expensive
  • might be too heavy for warmer months

Coyuchi

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.

Fast Facts

  • Shell Material: cotton percale
  • Fill Material: 360gsm organic cotton batting
  • Care Instructions: machine-wash on the gentle or delicate cycle. Line dry or tumble dry low.

Best Comforter Set

18. Bedsure Cooling Comforter Set

What We Like

  • reversible microfiber design
  • set includes two pillow shams
  • good color range

What We Don't Like

  • low durability

Bedsure

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. Oh, and thanks to Prime delivery, you can have this under $50 set in just two days—and return it for free if it doesn’t live up to your expectations.

Fast Facts

  • Shell Material: brushed microfiber 
  • Fill Material: polyester
  • Care Instructions: machine-wash on cold and gentle. Air dry only.

Best Organic Comforter

19. Avocado Green Alpaca Duvet Insert

What We Like

  • GOLS-certified cotton percale and alpaca fibers
  • naturally temperature-regulating
  • moisture resistant
  • comes in two weights

What We Don't Like

  • expensive
  • spot-clean only

Avocado

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.”

Fast Facts

  • Shell Material: organic cotton percale
  • Fill Material: Peruvian alpaca fiber
  • Care Instructions: spot clean only.

How to Choose the Right Cooling Comforter

  • Cooling Technologies: Check the package: What kind of cooling tech does it offer, and what does it actually do? HydroCool, for example, features moisture-wicking fibers that prevent you from getting sweaty. Another popular feature, Outlast, is a NASA-developed “phase change” material that helps regulate your body temperature, preventing sweat from happening in the first place.
  • Hypoallergenic: Some materials used in comforters may cause allergic reactions. Should you have allergies, be sure to look for hypoallergenic options, especially when it comes to down. You’ll likely want to choose a down-alternative.
  • Down-Alternative: More often than not, you’ll find blankets with down-alternatives that feel just as fluffy as traditional down blankets. They typically trap less heat than all those down feathers, plus they tend to be less expensive.
  • OEKO-TEX Certified: To be OEKO-TEX certified, textile and leather products must hit strict OEKO-TEX safety and environmental requirements. More specifically, they must be free of harmful substances like arsenic, lead, formaldehyde and pesticides, and meet environmentally and socially responsible production standards.

What Is the Best Cooling Fabric for Hot Sleepers?

  • Cotton: Cotton is one of the most popular cooling fabrics because it’s breathable, inherently soft, great for anyone with sensitive skin and incredibly versatile, with several different weaves to choose from (according to experts at Parachute). In terms of cooling, the most popular weaves include long-staple Egyptian cotton (the créme de la créme of luxury bedding), organic cotton (planted from non-GMO seeds) and jersey (the same soft material used in many T-shirts).
  • Bamboo: Bamboo is one of the most breathable materials around, thanks to its open-cell construction. It’s also one of the most eco-friendly, since it grows quickly and doesn’t require pesticides or irrigation. But that’s not all: “Cotton can be extremely soft [at] high thread counts, but bamboo is naturally softer, stronger [and] more absorbent,” explains Wanda Thompson, creator of Householdwonders.com. Not to mention that it absorbs five times more carbon and produces 35 percent more oxygen (making it a great moisture-wicking option for sweaty sleepers).
  • Eucalyptus: Eucalyptus Tencel (a branded form of lyocell) is known for its sustainable manufacturing processes. It’s the most popular iteration of Eucalyptus material, where “[tencel is] one of the most environmentally responsible and eco-friendly fabrics in the world,” according to Elle Liu, founder of Eucalypso. “The weave creates a luxuriously soft, smooth texture, similar to silk. And sheets made with eucalyptus are naturally hypoallergenic and antibacterial.”
  • Linen: “Linen is a go-to fabric for keeping cool,” writes PureWow’s former commerce editor, Brianna Lapolla, in a round-up of the best linen sheets. “The fabric's unmatched breathability is thanks to the fact that it's loosely woven from flax fibers (which are more hollow than cotton fibers), [and] allows air to circulate more freely.” Plus, aside from it being the world's strongest natural fiber (30 percent stronger than cotton), “it can absorb up to 20 percent of its weight in moisture [and] it's so durable, you hardly have to worry about upkeep. Linen can be tossed in the washing machine with cold water when it's time for a wash.”
