The dog days of summer bring some of the year’s worst heat and humidity. Bad news if you already sleep hot. A cooling comforter can make your bed feel less stuffy by using breathable materials that help prevent heat from building up overnight. You've probably been there—kicking off your comforter at 2 a.m. because you're sick of tossing and turning in damp sheets. Nothing ruins a good night's sleep like sweating through most of it. So, when turning on the AC no longer cuts it, it's time to call in some reinforcements with a cooling comforter (to be combined with cooling sheets, of course).

A cooling comforter has one job: keep your bed from turning into a sauna. The right one lets body heat escape, helping you stay cool while you sleep without giving up that cozy, tucked-in feeling.
A comforter’s weight, measured in grams per square meter (GSM), can make a big difference. Lower-GSM comforters generally feel lighter and sleep cooler. "As a rule of thumb, 150 to 350 GSM is good for summer months or hot sleepers, and 500 to 700 GSM is ideal for winter and cold sleepers," says Carleara Weiss, PhD, MS, RN, a member of the American Academy of Sleep Medicine. If you're somewhere in the middle? Opt for something between 300 and 400 GSM, she suggests. With all that in mind, here are the eight best cooling comforters of 2026.

What to Consider
Fill
You don't have to sacrifice that cloud-like feel just because your comforter is cooling or lightweight. Instead, you should look for a fill that's adjustable and contours around the body while sleeping so that it feels luxurious, soft, and light on the body, says Steinnes. To achieve this feeling, it's best to opt for a down alternative fill, as real down can often trap heat.
Shell Materials
As the outermost layer of the comforter, the shell material can make a difference in your cooling experience. Consider comforters made with breathable materials, like cotton or bamboo viscose, and avoid stuffy materials such as polyester or microfiber.
You should also make sure that your comforter shell material excels at quickly drying sweat or preventing it from forming. Comforters made with bamboo viscose do this well, since the material offers great ventilation, allowing it to absorb and dry sweat quickly.
Cooling Tech
When shopping for a comforter, make sure its description lets you know how it cools, whether through cooling materials, like bamboo or eucalyptus, or thermo-regulating technology. One example of a temperature-regulating feature is 37.5 Technology, which uses activated particles added at the fiber level to increase the surface area of the material, therefore aiding in removing sweat vapor before it turns to liquid.
Trial Period
Like mattresses, pillows, and even sheets, some brands offer a trial period that lets you test out a cooling comforter and return it if it’s not a good fit. For example, our top pick from Silk & Snow comes with a 100-night trial.
While this is a standard practice with large items like the best mattresses, it’s less common for comforters, so be sure to read the fine print for buying. Furthermore, if you opt to buy a comforter from Amazon, it likely won’t come with a trial period.
How We Selected
I’m a hot sleeper myself and have learned through trial and error what makes a good cooling comforter. I selected the above picks from my years of testing using the parameters above, comparing materials, trial periods, cooling technology, and certifications. I also evaluated customer reviews, pulling a five-star example for each comforter that explains why it’s so great from someone who has tried it firsthand.
Can you use a cooling comforter year-round?
If you want to, yes! Many cooling comforters are made with temperature-regulating features, which allow them to adapt their warmth to what your body needs. They can absorb and redistribute just enough heat to keep your body at a comfy temperature while sleeping.
If you don't feel like your cooling comforter is warm enough for the winter but still want to use it, layering it with another warmer blanket or quilt is always an option.
