For side sleepers who can't get it dark enough

If you sleep on your side, you already know

Most masks were designed for people lying flat on their backs.

So the moment you roll onto your side, the thing that was supposed to give you total darkness turns into the reason you're awake at 3am. Sound familiar?

It leaks light at the nose

Flat masks gap where your nose meets the pillow — so the streetlight, the sunrise, or your partner's phone still gets in.

It presses into your eyes

Roll onto your side and the mask pushes into your eyeball. You wake up with blurry vision and creases across your face.

It gets hot by 2am

Cheap fabric traps heat against your face until you rip it off in your sleep and lose the darkness anyway.

The velcro is loud

That scriiitch of velcro against your pillow every time you move — and the strap that slides off by morning.

What we're building

Four things a side sleeper's mask has to get right.

Everyone claims "side-sleeper comfort." The 1-star reviews at every price point say nobody delivers it. Here's the build we're testing to fix that — in this order:

1
Low-profile flexible cups that recover their shapeDeep enough to keep pressure off your eyes, low enough that lying on your side doesn't crush them into your face.
2
A silent sliding buckle — zero velcroNo scriiitch against the pillow at 3am, and a strap that actually stays put till morning.
3
Cool ice-silk outerBreathable fabric meant to stop the 2am heat build-up that makes you tear the mask off.
4
A nose baffle to kill the bottom light leakThe exact gap where cheap masks fail the "100% blackout" claim — closed off.

Straight talk: our samples are still in testing. These are the specs we're chasing, not finished claims. Founders get a vote on the final build — that's the whole point of joining now.

Benchmarked against the market's best

We bought the top masks and put them through a gauntlet.

No spin. These are our in-progress findings from real nights and bench tests — the honest baseline the founder kit has to beat before we'd ever ask you to buy it.

Mask	Blackout	On your side	Where it falls short
The $39 premium mask	~95% light blocked	Lifts & gets uncomfortable	Great blackout, but rides up on your side and is basically impossible on your stomach.
The volume best-seller	~90% coverage	Better than the $39	Feels nicer on your face and side-sleeps better — but leaves a small gap at the nose.
Testing is ongoing and we'll keep updating. We won't claim our mask beats these until it wins the gauntlet on camera — that's a promise, and it's why this is a waitlist and not a checkout.

I sleep on my side, and I got tired of masks that don't. Right now I'm doing this the unglamorous way: I bought the best-reviewed masks on the market and I score them every single morning — light leaks, pressure on the eyes, how they hold up when you roll over. Factory samples are on my desk being measured with calipers. Nothing goes to the founder batch until it beats the best of them on camera. That's the deal, and the first 100 people on this list get to hold me to it.

2023

A study published in Sleep — summarized by Harvard Health — found that wearing an eye mask overnight improved people's next-day alertness and memory compared with sleeping exposed to light. Darkness isn't a luxury. It's leverage on tomorrow.

That's the risk reversal we intend to launch with. We can't make it an active promise yet — because nothing's for sale yet — but it's the standard we're holding the product to before we'd ask for a dollar.

Straight answers

Questions before you join

Am I buying anything right now?

No. There's no checkout and no card field on this page. You're joining a founder waitlist. If the concept passes our testing and the first batch goes live, you'll be the first to hear — and you decide then whether you want one.

What does "the batch goes live" mean?

We're validating demand before we buy any inventory. If enough side sleepers want this — and our samples pass a real head-to-head test against the top masks — we'll produce a first run capped at 100 units. If it doesn't pass, we won't make it, and we'll tell you honestly. Either way you've risked nothing.

Why is it capped at 100?

Because we're a small operation testing a real product the honest way — not pretending to have warehouses of stock. The first run is genuinely 100 numbered units so we can nail the quality before scaling. No fake stock meters, no countdown clocks.

Are those real photos of the final mask?

Those are photos of a prototype sample we're currently testing — clearly labelled as such. The final kit isn't locked yet, which is exactly why founders get a vote on it. We'll only show final product photography once there's a final product.

What's the founder price and guarantee?

Founders lock $24 versus the intended $34 launch price, plus a free earplug upgrade. We plan to launch with a "60 Nights of Blackout or It's Free" guarantee. These are the terms we intend to offer at launch — not active purchase terms today, since nothing is for sale yet.

Will you spam me?

No. We'll email you about the founder batch and the occasional behind-the-scenes update on the build — and there's an unsubscribe link in every email. That's it.
