Nothing else worked
The weighted pressure just switches something off in my brain. I wake up and it's still on my face every single time. I finally feel rested again.

This is the one.
I run hot at night so I always assumed weighted masks weren't for me. The cooling side changed everything. I'm asleep within minutes now.

Truly a game changer
My brain used to race for an hour before I could sleep. Now I put this on and within minutes I feel my whole body let go. Best sleep investment I've ever made.

Best money I've ever spent
I already have blackout curtains, white noise, magnesium — the whole routine. This mask was the missing piece. I haven't had a bad night since.

Frequently Asked Questions
Most sleep masks just block light and stop there. This one goes further — the weighted beads apply gentle pressure across your eyes and forehead, signalling your parasympathetic nervous system to shift out of fight or flight mode and into real rest. It's the difference between lying in the dark with your brain still running and actually switching off.
That's exactly why we built it with two sides. The cooling side is made from smooth breathable nylon that stays cool against your skin all night. Most hot sleepers use the cooling side every night and never go back. Flip it to the warm plush side on cooler nights.
Yes — this is what makes it different from pod-style masks. The 180g wraparound design uses the weight itself to stay in place all night. No straps, no elastic, no clips. Side sleepers, back sleepers, restless sleepers — it stays on. Most people wake up and it's still on their face.
Most people notice it the first night. The weighted pressure activates your parasympathetic nervous system within minutes of putting it on — you'll feel your body physically let go. Falling asleep faster is the most common thing people report after their first use.
