ThermaWick IceSilk Weave

Still Cool at 3am. Not for Ten Minutes. All Night.

Frosté ThermaWick IceSilk cooling pillowcase, blue, shown on a pillow in a cool-toned bedroom

You've heard a promise like this before, and it let you down. Here's why this one's different: the ThermaWick IceSilk weave has no gel charge to run out, so it never stops pulling heat and sweat away. That's the whole reason you stop flipping the pillow at 3am looking for the cold side. If it ever turns into a sweat box on you anyway, we refund you in 5 working days. No runaround.

You know the feeling before you're even fully awake.

Soaked through. Pyjamas stuck to your skin. The pillow gone warm and heavy under your head. Duvet off, duvet on, duvet off again. Some nights you get up and change your nightclothes at 2am. Some nights you just lie there, damp, waiting for it to pass.

Then morning comes and you have to wash your hair again, because it looks flat and awful from being damp all night. You strip the bed for the fourth time this week. You're tired before the day has even started.

If this is you, here's the first thing to get straight: this is real. It isn't your fault. It isn't just a bad mattress or a stuffy room.

You are a hot sleeper. Maybe you're going through the change and the night sweats arrived along with everything else. Either way, your body runs hot at night, and no amount of "just get a fan" advice has ever touched it.

You are not imagining it. And you're not alone in it, either.

Rumpled damp bedding at early morning light, pillow flipped to its cool side, showing the aftermath of a hot night — The 3am aftermath: damp bedding, and the pillow already flipped to its cool side.

Why everything you've tried has let you down

Here's the part that makes it worse. You've already tried to fix this.

Maybe a gel pad insert. Maybe one of those "cooling" pillows from the supermarket. Maybe you paid a small fortune for a silk pillowcase because everyone said silk was the answer.

And for about ten minutes, it worked.

Then it didn't.

"It works for about an hour. Then it turns into a sweat box."

"Not worth the price. These are good but after 10 minutes they have to be turned over all night long."

"When you first put your face on the pillowcase, it does feel cool, but it only lasts for less than a minute."

"Cold but within 5 mins of being in bed there hotter than a Greek forest fire. Complete waste of money."

Sound familiar?

So you've quietly decided that this is just how the category works. Cooling products are cool for a few minutes, and then they're just... a pillow again. Marketing spin. Another waste of money to add to the pile.

We think that belief is wrong. And we can show you why.

The ThermaWick IceSilk weave

Here's what nobody tells you about gel pads and cool-touch cases: they don't run out of "cool" because the marketing is a lie. They run out because of how they're built.

A gel pad holds a fixed charge of cold, like an ice pack. Once your body heat and sweat have used it up, it's just a warm pad now. It has nothing left to give. That's why it works for about an hour and then quits.

A cool-touch or silk case feels cold for the first few seconds because of the fibre's surface. But the moment sweat sits on it and has nowhere to go, that surface heats straight back up. That's the "less than a minute" complaint, and it isn't a fluke, it's physics.

Frosté works differently, because it isn't trying to store cold. It's built to keep moving it.

The ThermaWick IceSilk weave does two jobs, continuously, all night:

1. A high heat-transfer fibre surface that draws warmth off your skin on contact, the cool-touch feel you notice the second you lie down.

2. A moisture-wicking, fast-drying structure that pulls sweat off the surface as it happens and lets it evaporate, instead of pooling and warming the fabric back up.

There's no gel pad hiding under the fabric to saturate. There's no charge to run down. The cooling isn't a layer added to the pillowcase, the cooling is the pillowcase. As long as there's a temperature difference between your skin and the weave, ThermaWick keeps working. That's why it doesn't quit at minute ten.

Let's be straight with you, because that matters more to us than sounding impressive: Frosté is cool, not cold. It's not a fridge, and it's not a medical cure for hot flushes, nothing bedding can stop that biological surge from happening. What it does is keep the surface you're actually sleeping on cool and dry, all night, so the hot flush is something you sleep through instead of something that wrecks the whole night.

Independently tested

Cool-touch tested: Q-max 0.35 W/cm2

Independently cool-touch measured: Q-max 0.35 W/cm2. The recognised cool-touch benchmark is around 0.2, so this sits firmly in genuine cool-touch territory.

Q-max is a measure of the cool feel the moment the fabric touches your skin, not a claim about the whole night. The all-night effect comes from the breathable ThermaWick IceSilk weave continuously wicking heat and moisture away rather than trapping it, and it's backed by the 60-Night "We Actually Pay" Cool Sleep Promise below.

This is for you, specifically

Maybe you're reading this thinking: fine, but my night sweats are proper night sweats. Soaked-through, change-your-clothes-at-2am night sweats. Not "a bit warm in summer."

Frosté was built with exactly that woman in mind.

If you're going through the change and the flushes are hitting most nights, we won't pretend a pillowcase can stop the flush itself, that's biological, and no bedding on earth touches it. What Frosté does is make the surface underneath you work with your body instead of against it, so the flush passes and you can get back to sleep instead of lying in a damp, overheated pillow for the rest of the night.

If you're just naturally a hot sleeper, always have been, this is the same fix, no diagnosis required. You don't need a reason. You just need the pillow to stop working against you.

This isn't a luxury beauty pillowcase and it isn't a self-cleaning hotel-sheet gimmick. It's built to solve one problem: you, overheating, every single night. Everything else is secondary.

Frequently asked questions

Cooling products always go cold for ten minutes and then turn into a sweat box on me. Why would this be any different?

Because it isn't storing cold, it's moving it. Gel pads hold a fixed charge that runs out. Frosté's ThermaWick IceSilk weave keeps pulling heat and moisture off your skin continuously, all night, because there's a constant temperature gap between you and the fabric to work with. Nothing to exhaust, nothing to saturate.

I've bought cooling pillowcases before and washing ruined them, or the seams fell apart. What about this one?

That's exactly why we built a hidden zip and a snug-fit seam, and why every order comes with the Wash-Right Care Card, simple steps to keep the weave and the seams intact, wash after wash.

Why should I pay more than a cheap £16 two-pack from the supermarket?

You can absolutely buy a cheap pack, and some people are happy flipping the pillow every ten minutes all night. Frosté costs more because the weave is engineered to keep working instead of quitting, and because we back it with a guarantee we actually pay out on. You're not paying for a brand name, you're paying for a mechanism that lasts the night.

If I put a pillowcase over my existing cooling pillow or pad, doesn't that cancel out the cooling?

With Frosté there's nothing to cancel out, because there's no separate pad underneath. The cooling is the pillowcase itself. You use it exactly like a normal pillowcase, no layering, no gel insert to think about.

Does this actually help with menopause hot flushes, or is that just marketing?

Nothing in bedding can stop a hot flush happening, that's biological. What Frosté does is keep the surface you're sleeping on cool and dry while the flush passes, so you're not also fighting a hot, damp pillow on top of everything else. It won't cure the flush. It will stop the pillow making it worse.

Is it actually cold, like a fridge, or just a bit less warm than a normal pillowcase?

Cool, not cold, and that's deliberate. Frosté isn't trying to feel like an ice pack, it's built to stay cool and dry for the whole night rather than icy for two minutes. If you want a genuinely comfortable temperature to sleep on for eight hours, cool-and-lasting beats cold-and-fleeting.

What if it doesn't work for me?

Then you tell us, and we refund you in full within 5 working days under the 60-Night Cool Sleep Promise. You keep the bonuses regardless. That's the whole promise, no small print.

Honest urgency

There's no countdown clock on this page, and there never will be. You've been lied to by fake urgency before, and we're not going to be one more brand that does it.

Here's what's actually true instead: the next hot night, or the next flush, is coming whether or not Frosté has arrived by then. That part isn't marketing, it's just how the next week goes. When a colour genuinely runs low on stock, we'll show that on the page, but we don't run a fake countdown or invent scarcity that isn't there. If you've been putting this off, the honest reason to stop waiting isn't a fake timer, it's that another night of stripping the bed at 4am is a night you don't get back.

Final word

You are not someone who has to just put up with this.

You're not "bad at sleeping," and you're not overreacting to something everyone else somehow copes with fine.

You're a hot sleeper who has tried the gel pads, the silk, the supermarket packs, and you're still here, still looking, because you haven't found the one that actually works yet.

That's not a failure. That's exactly the kind of person who finds the right fix, because you didn't settle for the first thing that felt cold for ten minutes and quietly gave up.

Frosté was built for that exact search. Not a cure. Not a fridge. A pillowcase engineered to stay cool and dry the whole night through, and a guarantee that means it if it doesn't.

Tonight doesn't have to be another one you sleep through damp.
