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.

What IS QMAX?
Qmax measures how cool a fabric feels instantly when it touches your skin. The higher the value, the faster the heat transfers, and the "cooler" the fabric feels.

measuring anti-static properties
This measures how long the fabric clings to a surface due to static electricity after being rubbed against another material. It simulates a shirt sticking to your body or pants sticking to your leg.

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.
Antimicrobial
Evercool®+ is permanently 'self-cleaning'; embedded with naturally antimicrobial silver yarn that protects the bedding from odor and bacterial growth.
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®+ Pillowcase is actually cool, really cool. It has one of the highest lab tested Qmax values on the market at 0.36 (cotton is 0.11 and silk is 0.19). The higher the Qmax value, the higher the cool to the touch effect. The best part is that the Evercool®+ fabric achieves these values without using any cooling additives, nano-particles or chemicals. The sheets also have IONIC+ Antimicrobial Technology woven into the fabric to help prevent microbes from accumulating on the fabric, keeping the sheets fresher and cleaner longer.
The Evercool®+ Pillowcase consists of two main ingredients: Nylon and spandex blend and IONIC+ Antimicrobial Technology Silver Yarn. The advance nylon used offers the cool to the touch effect, high moisture wicking capability and silky touch. The spandex used gives the outer shell a little stretch to improve on the anti-sagging properties and machine washability. The IONIC+ Antimicrobial Technology silver yarn provides antimicrobial properties. It is permanent, never washes out and helps the fabric stay fresher, cleaner, and lasting longer.
Each order comes with two Evercool®+ Pillowcases.
With our one-year limited warranty on all our products, you're guaranteed high-quality, well made products.
