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.
