Felt daft ordering it
Felt a bit daft ordering it, if I'm honest. Put it on for the first time and my wife took a photo, which is fair enough. It works though.

BEFORE YOU DECIDE
Isn't this just a cold hat?
Most of them are — a thin beanie with a gel pack pushed inside. Cold in one patch, damp against your skin, and it smells of the freezer within a week. This is one engineered piece: 360° gel around the whole head, true blackout across the eyes, thinner gel where it meets your ears, and a sleeve that unzips and washes while the gel core stays dry. Four of the six complaints people make about the cheap ones are things we built out.
How long does it actually stay cold?
About twenty minutes of proper cold, then it fades. That is true of every gel cap on the market whatever their adverts imply — it is the physics of gel, not a flaw in one brand. The answer is rotation: one on your head, one in the freezer, swap and go again.
What if it doesn't work for me?
Sixty days, so you judge it on real bad days rather than a curious try-on. If it doesn't make them more bearable, tell us — the refund is the full amount, and the eye pillow, the pouch, the Ear Band and the Protocol stay with you.

Fits my actual head
Every other one I've had either wouldn't go over my hair or froze my ears off. This does neither.

I'm the worst person to sell to
Look, I'm the worst person to sell to. I've tried the magnesium, the daith piercing, two different mouthguards. This one stayed. I don't know why it works for me and not the others and I've stopped trying to work it out.

Honest four stars
Four stars because I wish it lasted longer. Everything else I like. I've since got a second and I've stopped noticing the problem, which probably tells you something.

The light stops screaming
Best way I can put it is the light stops shouting at me. Cap on, pulled right down, curtains already shut. Twenty minutes of being somewhere else.

The vice loosens
Two minutes and the cold gets through and that vice feeling starts to let go. It doesn't stop the pain, I'm not going to pretend it does. But it turns a nine into something I can lie down and get through.

Since 1873
Prescribed in 1873. Perfected for the freezer.
It was never “just a headache.” The first great migraine textbook knew that in 1873 — it prescribed ice and darkness. We industrialised it.
Two minutes in: The Melt.
The cold soaks through. The vice loosens. The light stops screaming. Sufferers describe it the same way every time: the pain doesn’t vanish — it melts down to something you can ride out.
That’s The Melt. Cold, dark, quiet and a gentle pressure that’s on your side, all arriving at once. It’s what you’re buying.
Bad days do not book ahead.
GO DARK — from £49.95
Why we built it
The oldest migraine prescription, rebuilt by the people who needed it.
Every era of medicine has ended up in the same place: ice and darkness. The 1873 textbooks prescribed it; today's clinics still do. It never stopped working — it just never got engineered properly.
So we did the unglamorous part. We read the complaints on every American cap — the freezer smell, the frozen ears, the cold that quits early — and built each one out. Not a miracle. A better version of the thing that already works.
That is the whole pitch. Cold, dark and quiet, engineered to arrive together — and a guarantee that lets you judge it on a real bad day, not in a bright kitchen.

The honest minutes.
Cold caps stay properly cold for about 20 minutes. All of them. Anyone who says otherwise is selling you one. That's why the Rotation Kit exists — one on, one freezing.

Built from the complaints
The complaints that built this cap.
“It smells like the freezer.”
Ours lives in its own sealed pouch. No freezer smells, ever.
“It froze my ears.”
Soft ear zones — plus the knitted Ear Band in every kit.
“The cold died in eight minutes.”
About 20 minutes, every cap on earth. So the kit carries two.
“One wash ruined it.”
The sleeve unzips and washes. The gel core never goes near water.
“Freezer-cold is too much for me.”
Run it fridge-gentle, or microwave-warm. Dual mode is the answer.

Before you order
What to expect.
-
Tonight
Kit in the freezer. Protocol on the fridge door. You are ready before the next bad day is.
-
The first bad day
Curtains. Cap on, halo down. Minute one is properly cold; minute two is The Melt. Not gone — survivable.
-
Week 3
The rotation is a reflex. The freezer pouch has a permanent shelf. You stop planning around the fear of the next one.
Sending it to someone?
You can't take the bad days away from someone you love. You can put this in their freezer.
You've probably watched someone you love disappear behind a bedroom door and been able to do precisely nothing. You still can't fix it. You can have this ready in their freezer before the next one.
Add a gift note at checkout — printed properly, in a quiet, deliberately non-medical box. The Worst-Day Guarantee travels with the gift: they judge it on a real bad day, and if it isn't right, neither of you loses anything.

Asked before every order.
How long does it actually stay cold?
Twenty honest minutes, then physics wins — gel warms, every brand's does. Rotation is the real answer: one on, one in the freezer, swap. It's why the Rotation Kit exists, and why most people pick it.
Will it fit my head — and what about long or thick hair?
One-size stretch, tested across a genuine range of head sizes and hair volumes. Long or thick hair works best pulled into a low, loose knot or left down — the cap stretches over it and several owners tell us it usefully holds their hair off their neck. The soft zones sit over the ears so they take gentle cold, not a freezer burn. If it genuinely does not fit you, the Worst-Day Guarantee covers it.
How do I wash it?
The outer sleeve comes off and machine-washes at 30 degrees. The gel core wipes clean with a damp cloth — never machine-wash a gel core; that is how the category's most famous one-star review happened. Between uses the cap lives in its sealed pouch in the freezer, which is why it never comes out smelling of last month's dinner.
Cold makes mine worse. Is this still for me?
You are a real segment, not an oddity. Two routes: keep the cap in the fridge instead of the freezer — a much gentler cold that many people prefer, especially around the ears — or use it warm: twenty seconds in the microwave turns it into the heat version. The Protocol card in the box covers both rituals. The blackout works exactly the same either way.
I'm pregnant and can't take my usual medication. Can I use this?
Many medication-restricted sufferers rely on cold and dark precisely because they are two of the few options left on the table. The cap is a gel cold pack and a blackout layer — nothing pharmacological, nothing absorbed. That said, we are a cap company, not your care team: check with your midwife or GP before adding anything to your routine.
How fast is delivery?
Free UK delivery, tracked, 4–8 days door to door — and you will have the tracking link from day one. No customs forms, no 7–18 business days waiting on a parcel from America.
What exactly does the guarantee cover?
Sixty days from delivery, so you judge it on real bad days — not a curious try-on in a bright kitchen. If they aren't more bearable, email us: full refund, no return label, no questions that are really accusations. The eye pillow, pouch, Ear Band and Protocol stay with you either way.
Is this a cure?
No. Nothing we could sell you is, and anyone implying otherwise deserves your scepticism. What the cap does is physical and honest: cold, dark, gentle pressure, quiet — the things sufferers already reach for, engineered properly and ready in the freezer. It will not stop the bad days coming. Owners tell us it makes them more bearable — survivable is the word that keeps appearing. That is the whole promise, and it is the only one we make.
Judge it on your worst day. Sixty days to decide.
