Best Cooling Comforters for Summer 2025

If you're constantly waking up sweaty, tossing the covers aside, or avoiding comforters altogether during summer—you're not alone. Hot sleepers often struggle to stay asleep as body temperature rises through the night, especially in warmer climates or poorly ventilated bedrooms. While lightweight bedding can offer some relief, finding a comforter that feels cozy without overheating is key to uninterrupted, restful sleep.

Among all the options we tested, the Breescape Cooling Comforter stood out as our top pick for Summer 2025. With a dual-sided design—featuring a cool-touch surface on one side and breathable softness on the other—it adapts to your body’s temperature and keeps heat from building up. The fill is lightweight yet plush, making it ideal for those who want the comfort of a traditional comforter without the sweat. Testers praised it for its balanced feel and how quickly it dissipated warmth throughout the night.

To find the best cooling comforters on the market, we spent over six months testing more than 50 comforters across a variety of brands and price points. Each model was evaluated for breathability, moisture-wicking ability, fabric feel, and wash durability. We also sent top contenders to consumer testers—many of whom identify as hot sleepers—to capture how they perform in real bedrooms, not just the lab.

1. Best Overall: Breescape Cooling Comforter

• Cover material: 69% Nylon, 20% Polyester, 11% Spandex (Cool side) | 58% Eco-Cosy® Viscose, 42% Nylon (Breathable side)

• Fill material: 30% Naia™ Acetate, 70% Polyester

• Cooling features: Dual-sided design with cool, moisture-wicking, breathable fabrics and lightweight fill

Among all the cooling comforters we tested, there’s absolutely no contest: The Breescape is the best cooling comforter on the market right now. It stands out for its innovative dual-sided design—one side provides an immediate cool-to-the-touch sensation, while the other offers superior breathability for balanced temperature regulation. The premium blend of eco-friendly and high-performance fibers works together to wick away moisture effectively, keeping you dry and comfortable throughout the night. Its lightweight fill ensures warmth without overheating, making it a versatile choice for a variety of sleepers.

TESTING NOTES: Testers praised Breescape’s ability to deliver consistent cooling without feeling clammy or heavy. One shared, “The cool side truly feels refreshing the moment it touches your skin, and the breathable side is perfect when you want a lighter layer.” Another noted, “It’s soft, durable, and noticeably helps reduce night sweats, which has been a relief during menopause.” This comforter impresses by combining advanced cooling technology with everyday comfort and eco-conscious materials.

2. Softest: Rest Evercool Cooling Comforter

• Fill material: Sorona and Tencel fiberfill

• Cover material: 90% nylon, 10% spandex

• Cooling features: Heat- and moisture-wicking fabric with a soft, smooth handfeel

If softness is your top priority in a cooling comforter, the Rest Evercool is worth considering. Its silky cover feels smooth and cool the moment it touches your skin, and the lightweight Sorona-Tencel fill offers gentle warmth without the weight. The combination of materials creates a surface that feels more like athleticwear than traditional bedding—great for hot sleepers who still want a soft and cozy experience.

TESTING NOTES: Testers highlighted the comforter’s soft handfeel and quiet, cling-free fabric. One shared, “It doesn’t crinkle or bunch, and the smooth cover stays comfortable even when I turn a lot at night.” Another noted, “It helped me stay drier on humid nights, though I wouldn’t say it’s ice-cold.” While it may not offer dramatic temperature drops, its fabric feel and moisture control make it a solid choice for people who want cooling performance wrapped in softness. If Breescape is out of stock, Rest makes for a reliable backup. While it doesn’t deliver the same intense chill, it still provides noticeable temperature relief and gets the job done.

3. Best Budget: Elegear Cooling Comforter

• Fill material: Nylon/spandex and polyester

• Cover material: Down alternative polyester

• Cooling features: One cool-to-the-touch moisture-wicking side, lightweight fill

The Elegear cooling blanket is a lightweight, double-sided option designed for year-round use—except during very cold winters. One side features a smooth, cool-to-the-touch fabric that performed well in our moisture-wicking tests, while the reverse side offers a soft, brushed finish to provide some extra warmth on cooler spring or fall nights. It’s intended to be used without a duvet cover and comes in a range of simple, solid colors. Machine washable, it’s best to hang dry in the shade to maintain its quality over time.

TESTING NOTES: Testers appreciated the cooling fabric, especially those prone to night sweats who found the cool side comforting. The lightweight design was also praised for feeling unrestrictive and not bulky. However, some noted that to maintain the cooling effect, the comforter needs to be shifted regularly or paired with a fan—something a few testers found slightly inconvenient and wished the cooling lasted longer.

4. Best Down: Brooklinen Down Comforter

• Cover material: 100% Cotton

• Fill material: Down

• Cooling features: Lightweight fill for breathability

If you love the feel of traditional down but tend to sleep hot, Brooklinen’s lightweight down comforter offers a great balance of plushness and breathability. It’s available in three fill levels, and the lightest version (650 fill power) is especially suited for warmer months or year-round use in milder climates. The baffle-box construction helps keep the down evenly distributed, and it comes with a one-year return window—longer than most. Just note: it’s recommended to spot clean or dry clean only.

TESTING NOTES: Our testers found the comforter noticeably lighter and airier than many other down options. One described it as “sleeping under a soft, weightless cloud,” while another, who tested the All-Season version, said, “It felt so plush, but surprisingly not stuffy. I didn’t overheat like I usually do with down.” For those wanting a single comforter that works across seasons, the All-Season version also performed well at regulating body temperature. This one isn’t for you if you want a silky, cool-to-the-touch fabric or something you can toss in the washing machine.

5. Best Lightweight Comforter: Slumber Cloud UltraCool Comforter

• Cover material: 89% cooling nylon, 11% spandex jersey

• Fill material: Outlast-infused down-alternative fiberfill

• Cooling features: Outlast® temperature-regulating technology, moisture-wicking cover

If you're looking for a cooling comforter that feels light as air but still offers a bit of plushness, the Slumber Cloud Lightweight Comforter is a solid pick. It’s designed with Outlast® technology, originally developed for NASA, which helps regulate body temperature by absorbing, storing, and releasing heat. The result? A cooler, more stable sleeping environment throughout the night.

The fill is thinner than traditional down alternatives at 300 gsm, but still provides just enough cushioning. The jersey-knit cover feels smooth and slightly stretchy — though a few testers mentioned it can be a bit slippery depending on your sheets.

TESTING NOTES: Several testers noted that this comforter struck a rare balance between feeling weightless and still substantial. One shared, “I expected something super thin, but it had just enough loft to feel cozy without weighing me down.” Another tester said, “It helped me sleep more comfortably through hot flashes without waking up drenched.”

And for those who prefer low-maintenance bedding, many appreciated how easy it was to wash and dry — especially compared to heavier or down-filled alternatives.

Our Testing Process

We didn’t just try these comforters once and call it a day. Over several months, we put each one through its paces in real bedrooms—checking in at one, three, and six months to see how they performed over time.

We looked closely at construction quality, making sure seams stayed strong and fill didn’t bunch up. For duvet inserts, we tested whether they stayed put or shifted around. Comfort was key: we paid attention to how cool or warm we felt, whether any sweating happened, and if the comforter stayed breathable throughout the night.

We also took note of any noise from the materials and how easy the comforters were to clean—yes, we spilled coffee on them! Plus, we washed each comforter at least once to see how they held up in real life.

Finally, we gathered feedback from a range of sleepers, including those who tend to overheat or sweat at night, to get a full picture of how these comforters perform for different needs.

This thorough approach helped us find options that are not just cool on paper but actually deliver night after night.
