I'm experiencing perimenopause and was having night sweats. That hasn't happened since I started using these sheets!
The cooling was unlike anything I've experienced before and had an amazing effect on my sleep.
I no longer have to keep one foot out from under the blanket.
My sleep has improved tremendously. I feel cooler with the new sheets and comforter.

The Science of Evercool®
Cool-to-the-Touch
Evercool® is a proprietary fabric that instantly cools and regulates your body temperature for all night comfort, making it the best bedding for hot sleepers.
Smooth & Soft
Engineered from ultra-fine, smooth fibers 75x thinner than hair, Evercool® is frictionless and glides effortlessly across your skin.
Moisture-Wicking
Moisture is pulled and evaporates immediately through microscopic channels for uninterrupted, sweat-free sleep.
Breathable
Evercool® is designed to actively release trapped heat while allowing fresh, cool air to circulate throughout the night for optimal thermal regulation.
Rest® Labs
Each Evercool® product undergoes extensive R&D to ensure it’s optimally cool, comfy, and clean.
01 Thermal Conductivity Evercool’s high-conductivity polyamide yarns outperform fabrics like silk, bamboo and cotton, keeping hot sleepers cool and comfortable.
02 High Contact Fabric Surface Engineered for a buttery-soft touch that gets even smoother with every wash.
03 Moisture Wicking By knitting ultra-fine, smooth fibers at high densities, the resulting Evercool® fabric has significantly more surface area that touches your skin. This maximizes heat dispersion and allows for faster sweat wicking.
04 Breathability Independent airflow testing shows Evercool® is light, airy, and breathable for uninterrupted rest.
How Evercool® Compares
Evercool® outperforms fabrics like silk, bamboo and cotton, keeping hot sleepers cool and comfortable all night for uninterrupted rest.

Frequently Asked Questions
The Evercool® Cooling Comforter cools through the structure of the fabric itself, not through chemical coatings or cooling additives, so the effect does not wash out or fade. In third party testing by SGS, the Evercool® fabric measured a Qmax score of 0.433 watts per square centimeter. Qmax measures how cool a fabric feels the instant it touches your skin. The comforter has also won the Good Housekeeping Bedding Award four years in a row, from 2023 through 2026.
In SGS lab testing, Evercool® fabric measured a Qmax score of 0.433 watts per square centimeter, compared to 0.19 for silk, 0.15 for bamboo, and 0.11 for cotton. Qmax measures how cool a fabric feels on contact, so Evercool® feels noticeably cooler the moment you get under it. It also breathes better than silk, wicks moisture through the night, and unlike silk it is fully machine washable.
Yes. The Evercool® fabric pulls moisture away from your skin and dries quickly, while the cool touch surface helps take the edge off the temperature spikes that wake hot sleepers. Its performance has been validated by SleepScore Labs, and it is one of the most common reasons customers choose Rest.
Yes. The Evercool® Cooling Comforter regulates temperature rather than simply feeling cold. In warm months the cool touch fabric and moisture wicking keep you from overheating, and in cooler months it works as a comfortable everyday comforter on its own or layered with a blanket.
No. The cooling in the Evercool® Cooling Comforter comes from the structure of the fiber itself rather than a coating or additive, so there is nothing to wash out or degrade. The comforter keeps its cool touch wash after wash, and it is covered by a one year limited warranty against manufacturing defects.
Yes. The Evercool® Cooling Comforter is hypoallergenic and certified to OEKO-TEX® Standard 100, Product Class I, the strictest class of the standard, which applies to products safe for babies and toddlers. Independent testing by SGS found no detectable PFAS and no detectable BPA.
The Evercool® Cooling Comforter is fully machine washable at home. Machine wash cold, then tumble dry on low heat or drip dry. Do not use bleach.
The Evercool® Cooling Comforter comes in three sizes: Twin and Twin XL at 68 by 90 inches, Full and Queen at 90 by 90 inches, and King and California King at 106 by 90 inches. It comes in six colors: Aqua Blue, Arctic White, Snow Ivory, Cool Gray, Lavender Breeze, and Midnight Blue.
No. The Evercool® Cooling Comforter is designed to be used on its own, so the cool touch fabric rests directly against your skin, and it is machine washable so it does not need a protective cover. If you prefer to use a cover, choose a breathable one to preserve the cooling feel.
Every Evercool® Cooling Comforter comes with a 30 night trial, so you have 30 days from delivery to start a return at returns.rest.com. Exchanges and store credit are always free. Refunds carry a 10 dollar flat fee per order and arrive within 14 to 21 business days, and return shipping is covered within the United States. The comforter is also covered by a one year limited warranty against manufacturing defects.
