Pillow surface temperature
Standard cotton pillowcase vs. cooling fibre after 20 minutes of contact. Watch it drop. ↓
Why you sleep hot
Your head releases heat all night. Ordinary pillowcases absorb it and radiate it straight back — which is why you keep flipping the pillow at 2 a.m.
Cooling fibre has a high heat-transfer coefficient: it pulls warmth away from your skin on contact and disperses it, keeping the surface measurably cooler until morning.
Built for hot sleepers
Ultra-fine woven fibres wick moisture 3× faster than cotton, so night sweats evaporate instead of soaking in. The smooth surface is also gentler on skin and hair.
Zero-fuss ownership
The cooling effect is woven into the fibre itself — not a spray-on coating that washes out. Cold machine wash, hang dry, and it performs like night one.
"I stopped flipping my pillow"
First thing that actually stays cool past midnight. Ordered two more for my partner.
"Night sweats basically gone"
I wake up far less drenched and the case dries out incredibly fast. Washed it six times, still icy.
"Wish I'd bought the 4-pack"
The fabric genuinely feels cold when you first lie down. Buying the family bundle next.
The fibre has high thermal conductivity, so it transfers heat away from your skin on contact instead of trapping it like cotton. Nothing to charge, chill or refill.
No. The effect comes from the fibre, not a coating, so it survives unlimited washes. Cold machine wash, hang dry, skip the fabric softener.
Sleep on it for up to 30 nights. If you're not noticeably cooler, email us for a full refund — no return shipping games, no restocking fees.
Try it on your own pillow, in your own bedroom, for a full month of nights. If you're not sleeping cooler and waking up drier, we'll refund you in full. The risk is ours — the cold side is yours.
