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.
Coolness Test (Q-max)
0.445 W/cm²
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.

MEASURING ANTI-MICROBIAL PROPERTIES
The antimicrobial test follows ISO 20743 standards, which measures measures the difference in bacterial growth between a treated fabric and standard cotton.

The Science of Evercool®
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.
Engineered from ultra-fine, smooth fibers 75x thinner than hair, Evercool® is frictionless and glides effortlessly across your skin.
Moisture is pulled and evaporates immediately through microscopic channels for uninterrupted, sweat-free sleep.
Evercool® is designed to actively release trapped heat while allowing fresh, cool air to circulate throughout the night for optimal thermal regulation.
Evercool®+ is permanently 'self-cleaning'; embedded with naturally antimicrobial silver yarn that protects the bedding from odor and bacterial growth.
Rest® Labs
Cool-to-the Touch Evercool’s high-conductivity polyamide yarns outperform fabrics like silk, bamboo and cotton, keeping hot sleepers cool and comfortable.
Smooth & Soft Engineered for a buttery-soft touch that gets even smoother with every wash.
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.
Breathable Independent airflow testing shows Evercool® is light, airy, and breathable for uninterrupted rest.
Antimicrobial 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 for uninterrupted rest.
