Best overall

Our undisputed champion for heatwave survival. The Rest Evercool Comforter quickly became a standout favorite during testing. It's one of the coolest comforters I've ever tested — my husband and I never woke up hot or sweating, even during a heat wave. Incredibly lightweight, it feels soothingly light and airy, making it a joy to snuggle into thanks to its soft, silky, smooth nylon-and-spandex shell.

A high-tech fabric blend that actively banishes sweat. It's reversible and comes in a variety of colors, including my personal favorite, aqua blue. Crafted from a blend of natural Tencel and Sorona, an eco-friendly fiber made from renewable, plant-based materials, the Rest comforter offers exceptional breathability and moisture-wicking capabilities. Washing it was a breeze, and it retained its shape perfectly without clumping, shrinking, or stretching.

Hypoallergenic, eco-friendly, and pet-friendly. The added benefits of a 30-night return policy (as long as it's in its original packaging), a one-year warranty, Oeko-Tex certification, and hypoallergenic properties make it even more appealing. I was pleasantly surprised to find no cat hair sticking to it — a bonus feature for pet owners.

A few quirks to keep in mind. It is strictly a comforter, lacks loops for use with a duvet cover, and can slide easily when paired with silky cooling sheets. As someone who doesn't typically run hot, I woke up feeling chilly at least once. Unlike me, my husband, a hot sleeper, reported waking up feeling comfortably cool throughout our testing period. Overall, though, the Rest Evercool comforter lives up to its promise for hot sleepers, effectively managing sweat and moisture for a truly restful night's sleep.

Runner up

The perfect compromise between high-tech cooling and traditional coziness. If you want the active temperature regulation of our Best Overall pick but refuse to give up the puffy, substantial feel of a classic duvet, the Slumber Cloud UltraCool Comforter is an exceptional runner-up. Compared to the others we tried, we loved how puffy and easy to maneuver it is. Throughout our testing, neither my husband nor I felt uncomfortably warm — the shell feels cool to the touch and effectively prevents heat buildup, keeping us comfortable all night long.

NASA-engineered temperature control. While many cooling blankets feel overly thin, this one provides a comforting, cozy weight without trapping body heat. The secret is the Outlast ClimaDry fiberfill—a phase-change material originally developed for NASA. Instead of just letting air pass through, this high-tech fill actively absorbs, stores, and releases your body heat, adapting in real-time to your temperature fluctuations.

Practical features and a lightweight alternative. Wrapped in a silky nylon-and-spandex shell, the blanket feels instantly refreshing to slip under. It maintains its shape beautifully after washing and features convenient corner loops for securing it inside a duvet cover. If the UltraCool sounds too puffy for your setup, Slumber Cloud also makes a lightweight version. We tested both and found them equally effective at temperature control, though we preferred the plushness of the UltraCool.

Best for night sweats

If waking up drenched is your biggest sleep hurdle, this is your solution. When night sweats are your primary concern, standard breathability isn't enough—you need active moisture wicking. The Sijo AiryWeight Eucalyptus Comforter proved to be an absolute game changer during our heatwave testing. I had one of the most refreshing and comfy sleep experiences using this comforter — even through warmer nights.

Eucalyptus is one of the best materials for hot sleepers. What really impressed me was how cool, silky, and soft it felt against my skin. The Tencel lyocell shell and fill are spun from eucalyptus wood pulp, a material that is naturally superior to cotton at absorbing moisture and dissipating heat. What really impressed us was the silky, cool-to-the-touch feel against the skin. Instead of waking up clammy, the eucalyptus fibers actively kept the heat at bay, ensuring we actually stayed dry all night long.

Bonus: It stays incredibly fresh. Because sweat can lead to bacteria buildup, Sijo treats this comforter with a silver-ion antimicrobial finish. It is also Oeko-Tex approved and certified asthma & allergy friendly, making it a pristine, eco-friendly choice that tackles overheating and sensitivities all at once.

Best value

A breathable, cloud-like feel without the premium price tag. The Silk & Snow Down Alternative Comforter was a delightful surprise in terms of both comfort and value. The lightweight version with a lower 175 GSM (grams per square meter) fill is ideal for those who tend to overheat at night. It strikes a perfect balance of cool and cozy. During our tests on warmer nights, it effectively dissipated heat, ensuring we woke up feeling comfortably cozy without overheating.

It's an excellent value. Though I was initially skeptical about its affordability compared to other options, I was pleasantly surprised by its luxurious feel and the quality of its materials. The 100% cotton exterior provides excellent breathability, and the vegan microfiber fill gives it a plush, down-like sensation. It's also available in all-season and winter weights of 375 GSM and 500 GSM, respectively.

It fits perfectly in a duvet cover. It has retained its softness and plushness remarkably well after multiple washes. Practical features like built-in corner loops to keep the duvet insert in place and a handy storage bag added to its functionality. I recommend the Silk & Snow to anyone looking for a cozy, budget-friendly cooling comforter that doesn't compromise on quality.

Best cool-to-the-touch

An immediate, icy-cool sensation the second you slip under the covers. I've really come to love Coop's products because they consistently exceed expectations, and its Cool+ blanket is no exception. If you're a hot sleeper looking for a refreshing, cool-to-the-touch option, the Cool+ Blanket is a fantastic choice. Coop's cooling technology disperses more heat than bamboo, silk, or other popular synthetics. The breathable yet super-soft blend of nylon and spandex maintains an optimal temperature, allowing heat to dissipate throughout the night.

Ultra-lightweight fabric that actively disperses trapped body heat. I've used this comforter everywhere, from the bed to the couch, and it remains lump-free even after multiple washes. It's light, airy, and silky-smooth, making every night's sleep a delight — and yes, I've continued using it even after testing. The comforter effectively dissipated heat, maintained a comfortable temperature, and cooled down quickly.

A neck-and-neck performance rival to our top pick. There was a slight initial odor, which vanished completely after the first wash. Now, it's perfect. It's become one of my favorites, offering exceptional quality and effectiveness at a fraction of the cost of other options. Deciding between this one and the Rest Evercool was tough. The Evercool is our overall pick because it's available in more color options, is hypoallergenic, and pet-friendly. But performance-wise, they come very close, both offering that refreshing, cooling sensation that hot sleepers seek for relief. It also lacks loops for use with a duvet cover.

Best bamboo

The ultimate eco-luxury splurge for a resort-quality bed. Thanks to its natural breathability, moisture-wicking properties, and temperature control, the Cozy Earth Bamboo Comforter is the top pick for anyone seeking a natural bamboo option that feels cool-to-the-touch. Its luxurious bamboo viscose fabric shell and fill are crafted to naturally regulate temperature.

Naturally temperature-regulating viscose that drapes like cool silk. Once unpacked from its beautiful canvas bag with leather straps, I was pleasantly surprised by how nicely it fluffed up. It molds around my body without trapping heat, providing a lightweight feel that keeps us cool and dry. Both my husband and I agree — it kept us refreshed, cozy, and feeling like royalty all night long. However, my husband, being the hot sleeper, did mention feeling a bit warm in the morning once during testing on a particularly humid night, though it was far from uncomfortably hot.

High maintenance, but worth the investment. The higher price tag forces me to be more conscientious about care and maintenance. Using a protective duvet cover is a must. Plus, since it's strictly spot or dry clean only, it's crucial not to risk washing it incorrectly if you're investing in this pricier option. Overall, it's an excellent choice for sleepers seeking naturally temperature-regulating, responsibly sourced bamboo suitable for year-round use.

Best down

The classic, fluffy down experience — re-engineered for summer. The Lands' End Essential Down Comforter strikes just the right balance between warmth and breathability. Its lower 550 fill power makes all the difference in maintaining a plush feel without trapping heat, making it a good choice for hot summer nights.

Lower fill power stops sweat but retains loft. I loved the feel, but it might not appeal to those looking for a thicker, more plush comforter — though cooling comforters are generally thinner to minimize heat retention. The cotton sateen shell adds a touch of elegance and evokes the cozy luxury of high-end hotels. We looked forward to snuggling into it every night during testing. What impressed us the most was its ability to stay light and airy despite the down fill.

The ideal compromise for those who sleep just slightly warm. My husband, the hot sleeper, mentioned getting a tad warm at least once during testing, but he quickly cooled down after briefly uncovering to cool off, then covered up again. The comforter features fabric loops for securing in a duvet cover and a handy storage bag. Overall, the Lands' End Essential Down comforter is a great option for those who prefer down fill. The comforter is both lightweight and substantial, making it suitable for warmer weather without overheating.

What to look for in a cooling comforter

To find the best cooling comforter, consider these essential factors along with your personal preferences and needs:

• Breathable fibers: According to sleep specialist Dr. Alex Dimitriu, natural and semi-synthetic fibers—like cotton, bamboo viscose, and Tencel lyocell (often marketed as eucalyptus)—naturally dissipate heat and wick away moisture far better than standard polyester. Look for these materials in both the outer shell and the fill to ensure maximum air circulation.
• Active cooling technology: If you suffer from severe night sweats, standard breathability might not be enough. Look for comforters engineered with phase-change materials (like Slumber Cloud's Outlast fiberfill) or specialized nylon/spandex blends (like the Rest Evercool) that actively absorb body heat and physically feel cool to the touch.
• Loft and weight: Cooling comforters are inherently thinner than traditional winter duvets to prevent heat trapping. Decide whether you prefer the ultra-lightweight, skin-hugging drape of a cooling blanket or a fluffier, traditional feel (such as a low-fill-power down or a specialized down alternative).

• Care requirements: Sweating at night typically requires more frequent laundering. If you want a low-maintenance bed, ensure the shell is machine-washable; otherwise, it may require spot cleaning or dry cleaning to maintain its integrity. When in doubt, check the tag.

• Return policy and trial period: Consider a comforter with a flexible return policy and trial period in case it doesn't meet your expectations. It's important to allow time to adjust to sleep products such as comforters and pillows, and to test their cooling effectiveness.We prioritized options that provide generous trial periods and flexible exchange and return policies.

How we test cooling comforters

Our testing methodology

I tapped into my experience as a certified sleep science consultant and connected with experts like Nishi Bhopal, MD, a board-certified psychiatrist and sleep specialist, Alex Dimitriu, MD, dual board-certified in psychiatry and sleep medicine, and Chris Winter, MD, a neurologist and sleep specialist to evaluate the top cooling comforters on the market, focusing on these key factors that impact sleep quality:

• Sleep quality testing: I spent 7 consecutive nights personally sleeping with each comforter in a climate ranging from 75 to 90 degrees (during a heat wave), taking notes on comfort and feel, temperature regulation, breathability, heat retention, and cooling capabilities. Additionally, my husband — a natural hot sleeper — joined me in testing the comforters and provided his perspective on how well they performed.
• Materials and certifications: We took note of each comforter's material, looking for the most innovative and effective cooling technologies, and looked for certifications for quality.
• Cleaning: We carefully read and followed care instructions, caring for the comforters multiple times to assess long-term durability. Some comforters in this guide are dry clean only or can be spot-cleaned.
• Shape retention: We dragged the comforters from the bed to the couch and noted any lumps or flattening after washing and sleeping with them. Some, like the Slumber Cloud UltraCool Comforter, require light fluffing after washing.

Cooling comforter FAQs

How do cooling comforters work?

Cooling comforters work through either active temperature regulation or passive moisture wicking. Active cooling comforters use high-tech phase-change materials (like specialized nylon or Outlast fiberfill) to physically draw heat away from your body. Passive cooling comforters use highly breathable, natural fibers like cotton, eucalyptus, bamboo to quickly evaporate sweat and allow trapped body heat to escape.

What is the best material for a cooling comforter?

The best materials for a cooling comforter are Eucalyptus (Tencel lyocell), Bamboo viscose, and specialized cooling nylon. According to sleep specialist Dr. Alex Dimitriu, these materials naturally dissipate heat and wick away moisture far better than traditional polyester or high-fill-power down

Can cooling comforters help with night sweats and hot flashes?

Yes, cooling comforters can help with night sweats and hot flashes by dissipating heat and creating a cooler sleep environment, but they won't necessarily eliminate them either, according to Dr. Nishi.

Are cooling comforters machine washable?

It depends on the comforter, since blankets with cooling properties can be delicate. Some are machine-washable, while others might require dry cleaning or spot cleaning. Always check the care instructions before washing and drying.

Can I use a duvet cover with a cooling comforter?

Yes, you can use a duvet cover over a cooling comforter, though some comforters may not have duvet loops. I recommend using a duvet cover made of breathable materials like bamboo or cotton to enhance the cooling effect. Putting a thick or synthetic duvet cover over a cooling insert will trap the heat and completely ruin the comforter's temperature-regulating properties. Note that some cool-to-the-touch blankets are designed to be used without a cover.
