Sia Silk is actively seeking give-back partners to expand their impact and continue their commitment to wellness and sustainability.

Founding Story

Evalee Gertz, founder of Sia Silk, has a background as a professional dancer. In her pursuit of peak performance, she dedicated herself to improving her overall health, focusing specifically on anti-aging techniques and the importance of quality sleep. Sleep quickly became a central part of her regimen, as she learned how essential it was for muscle recovery, cognitive function, and overall well-being. She realized that a sleep mask was one of the simplest and most effective ways to improve sleep quality.


However, after trying numerous masks, Evalee found herself dissatisfied. While synthetic masks provided good light-blocking properties, they often caused breakouts and contained chemical adhesives. Silk masks, with their anti-microbial properties, ability to help retain skin moisture, and support in cell turnover for anti-aging, didn’t fit well or provide complete darkness. Recognizing this gap in the market, Evalee created Sia Silk. She designed her masks with a unique shape for better fit, total blackout capabilities, and larger-than-standard eye cups to protect eyelashes—ensuring a more restful, skin-nourishing sleep experience.
