Some people just run hot.

Not everyone gets to just fall asleep and stay asleep.

Some of us wake at 2 or 3am already too warm, hunting across the pillow for a cooler patch that isn't there. Some of us deal with night sweats that soak through the pillowcase and leave us peeling off pyjamas at an hour when nobody wants to be awake. Some of us just sleep hot, every night, all year round, regardless of season or duvet weight.

We looked at what was already out there for this and mostly found the same thing: a gel pad or a cooling insert stitched inside a cover. It feels genuinely cold for the first five or ten minutes. Then it reaches your body heat, same as any other pillow, and you're back to flipping it. A short burst of relief, not a night of it.

Froste started as a fairly plain question: what if the cooling wasn't a pad you had to keep recharging, but was simply woven into the fabric itself, so there was nothing to run out?

Cooling woven in, not stuck on.

Our pillowcases are knitted from an ice-silk viscose and spandex blend, at a 400 thread count. There's no gel, no liquid insert, no pack to keep in the freezer. The fibre itself is what pulls heat away from your skin on contact, and what moves moisture off the surface as you sleep, so you're not lying in a damp patch by the middle of the night.

Because the cooling is part of the weave rather than an add-on, it doesn't have a charge to lose. It works the same at 2am as it does when you first lie down, and it works the same after fifty washes as it does out of the packet.

We'd rather say that plainly than let the marketing get ahead of the fabric. Froste is rated at Q-max 0.35 W/cm², which is the manufacturer's fabric specification for how much heat the material draws from your skin on first contact, the standard measure used across cool-touch textiles. It is not an independent lab test, and we don't claim it as one. It's the figure the mill gives us for this fabric, and it sits comfortably above the level generally used to call a fabric 'cool-touch' at all.

Q-max figure supplied by the fabric manufacturer as part of the material specification. It describes contact-cool on first touch, not a guarantee of temperature all night, and it is not an independently verified lab measurement.

A promise, not a slogan.

Every order comes with our 60-Night Cool Sleep Promise. Sleep on it for up to 60 nights. If it hasn't earned its place on your bed, tell us and we'll refund it, no case to build and nothing to send back.

We put a number that large on it because we're confident in the fabric, not because we need you to feel rushed into buying it. There's no countdown clock on this page and there never will be. If Froste is right for you, sixty nights is plenty of time to find out. If it isn't, that's a genuinely fair trade for both of us.

• 01

  Say what the fabric does, not what we wish it did

  Cool, dry, all night. Not a cure for anything, and we won't pretend otherwise.

• 02

  Back it with time, not pressure

  Sixty nights to decide. No countdowns, no manufactured urgency.

• 03

  Built to be washed, not babied

  A hidden zip, reinforced stitching, and a knit that's meant for weekly laundry, not fridge shelves.
