The 3am problem

You do not wake because you are tired. You wake because you are hot.

Cotton traps heat. By the small hours your pillow has soaked up everything your head has given off, and there is nowhere left for the warmth to go. So you flip it, get thirty cool seconds, and start again. If you run hot, or you are going through night sweats, that cycle can repeat all night.

Froste is woven from ice-silk, a smooth, dense fibre that pulls warmth off your skin instead of holding it. The surface feels cool the moment you lie down, and it keeps moving heat away rather than storing it. Cool, not cold. Dry, not clammy. Until the alarm.

Why it stays cool

Three things cotton cannot do.

i.

Pulls heat off your skin

Ice-silk has a high thermal-conductivity feel, rated by the manufacturer at a Q-max of 0.35 W/cm2. That is the cool-touch sensation you get the instant you make contact.

ii.

Moves moisture, stays dry

The weave wicks sweat sideways and lets it evaporate, so the surface does not turn damp and clammy the way a saturated cotton case does.

iii.

No flipping, all night

Because it sheds heat instead of storing it, there is no warm side to escape. You settle once and stay settled.

Sarah Manchester★★★★★

Finally sleeping through the heatwave

I was waking up at 3am drenched, flipping my pillow every ten minutes looking for a cool patch. This pillowcase actually stays cool all night, not just at first touch. Soft, smooth, and it's made the last few weeks of this UK heat bearable. Wouldn't go back to normal cotton now.

James Bristol★★★★★

Best change I've made for hot nights

I run warm even in winter, so summer in England has been brutal lately. This keeps my pillow feeling properly fresh and breathable all night. Light fabric, genuinely cool against the skin, and it's the first thing that's made a real difference to my sleep in ages.

Priya Leeds★★★★★

Was sceptical, genuinely impressed

Thought it might feel like the cooling gimmick pillowcases that go warm again after twenty minutes. This one doesn't. Soft, smooth, and it stays cool through the whole night, even during this heatwave. Washed it twice now and the effect hasn't faded at all.

Tom Cardiff★★★★★

Worth every penny

Fits my standard pillow perfectly, feels smooth against the skin, and the cooling effect is noticeably stronger than any pillowcase I've tried before. Small change, huge difference to how I've slept this summer. Already ordered a second one.

Emma Nottingham★★★★★

Still cool and soft after washing

Washed it before first use, worried the cooling feel might wash out. It didn't. Dried quickly too. The cool-to-the-touch feeling when you first lie down is exactly what got me through this heatwave without tossing and turning all night.

Amara Birmingham★★★★★

A proper upgrade for sensitive skin

I can't sleep on anything rough, so this was a gamble, but it's gentle on my face and doesn't trap heat the way my old pillowcase did. Genuinely breathable fabric. This heatwave would have been miserable without it.

Daniel Glasgow★★★★★

Simple, but makes a real difference

Not flashy, just does exactly what it promises. Noticeably cooler and smoother than regular bedding, and it's taken the edge off trying to sleep through this heat. Highly recommend if you're struggling with the UK heatwave like I was.

Sleep on it for 60 nights. If you still wake up hot, we pay you back.

Before you ask

The honest answers.

Is it actually cold, like an ice pack?

No, and we would not claim that. It is cool to the touch and it stays cool because it moves heat away instead of holding it. Cool and dry, not cold.

Will it help with night sweats?

It is made for hot sleepers and night sweats: a cooler, drier surface to sleep against. It is a pillowcase, not a medical device, so it will not stop a hot flush, but it gives the heat somewhere to go.

What size does it fit?

Standard UK pillows. It slips over your existing pillow like any pillowcase, so there is nothing new to get used to.

How do I wash it?

Cool machine wash, hang or tumble low. The cool-touch finish is the fibre itself, so it does not wash out.
