Light is the strongest signal controlling your sleep. Even small amounts tell your brain to stay alert and suppress melatonin — the hormone that drives deep, restorative rest.
The Nox Sleep Mask Core creates complete darkness from the moment you put it on. No gaps, no light leaks, no adjusting at 3am. The 3D-contoured shell holds a zero-pressure zone around your eyes, so there's no contact with your eyelids and nothing digging into your face — even for side sleepers.
At just 1.2 oz, the ice silk surface stays cool and breathes through the night. Wear it at home, on a flight, or for daytime recovery. Block the light, and your body does the rest.
Why It Works
Total Blackout
Blocks 100% of light, with no gaps around the nose.
Zero Eye Pressure
3D contoured cups never touch your eyelids.
All-Night Comfort
Lightweight ice silk, stays cool and in place.
Side-Sleeper Fit
Low profile won't shift or press when you turn.
Total darkness means deeper rest - so you rise sharp, not groggy.

INCLUDED FREE WITH EVERY ORDER
The Nox Sleep Protocol
A product blocks light. A system changes how you sleep. Every Nox order includes the Nox Sleep Protocol — a 12 page, science-backed guide to engineering your nights: light, temperature, breathing, timing, and the routine that ties them together.
It's the difference between owning a sleep mask and actually sleeping better.
