Why Cosyzz

Built Around Real Sleep

Total Blackout, Zero Eye Contact

Our 3D contoured designs create a dark chamber that blocks 99% of light without touching your eyelashes. Blink naturally, sleep deeply — no eye fatigue, no makeup smudging, no dry eyes from mask pressure.

Designed for Side Sleepers First

Most sleep masks are made for back sleepers. Ours aren't. Wide ear-covering bands eliminate strap dig-in. Ultra-thin side profiles don't bunch against pillows. Adjustable closures stay put, no matter how much you move.

Materials That Respect Your Skin

19mm mulberry silk preserves moisture and reduces the friction that causes sleep creases. Our breathable memory foam includes air holes to prevent overheating. Every material is chosen for 8+ hours of continuous contact.

Works Everywhere You Sleep

At home, in a hotel, on a red-eye flight, during a day nap — our masks are compact, lightweight, and designed for the full range of sleep environments. No learning curve. Just put it on and rest.

A Fit That Adjusts to You

Every mask features an adjustable closure or band sized for a wide range of head sizes. Nose cutouts and contours are shaped to minimize light gaps, delivering complete darkness regardless of your face shape or size.
