High Contact Fabric Surface

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.

Breathability

Breathability refers to a fabric's ability to allow air to pass through, which helps regulate body temperature. Evercool®'s knit structure maximizes airflow to release trapped heat while allowing fresh, cooler air to circulate throughout the night.

Knitted construction

Using a knitted fabric instead of a woven one, increases breathability.

Soft & Fine Fiber

Softness is defined as yielding readily to touch or pressure. Evercool® achieves this through densely knitted, ultra-fine fibers—just 1/75th the thickness of a human hair. Their exceptional flexibility allows them to conform to your body, providing a smooth and soft sensation.

High moisture regain rate

Moisture regain rate is a material's ability to absorb moisture from the air, which contributes to its softness. Evercool® wicks away sweat while maintaining its own moisture, preventing the fabric from feeling dry and scratchy, much like well-moisturized skin.

Unique washing and finishing process

Evercool® fabric undergoes an additional refinement process to enhance its softness. Multiple low-tension washes exfoliate and remove impurities, while a heat treatment with softener gives the fabric a smooth, silky, and distinctly waxy feel.
