THE SURFACE UNDER YOUR CHEEK
A cotton case holds the heat. This one moves it on.
Cotton is soft, and it’s good at holding things: warmth from your face, damp from your hair and skin. By 3 AM, that thin layer is the warmest part of your pillow.
Napfull’s cooling pillowcase is cool to the touch and draws warmth away from your skin instead of building it up. It works on the pillow you already own, so there’s nothing to replace.
HOW IT WORKS
Built for contact.
Heat moves from your skin into whatever it touches. The more fiber is in contact with your skin, and the better it conducts, the faster warmth is drawn away.
Conduct
Cool-to-the-touch fibers draw heat away from your face the moment you lie down.
Breathe
A thin, smooth knit lets warmth leave instead of settling into thick cotton.
Two in a pack
One on the pillow, one in the wash, so there’s always a fresh one ready.
WHO IT’S FOR
The easiest place to start
Which size is right for you?
MEASURED, NOT PROMISED
Cool you can measure: Qmax 0.40–0.45.
Qmax measures how much heat a fabric draws from your skin the moment you touch it. Around 0.15 W/cm² is where fabric starts to feel cool. Napfull’s fabric measures 0.40–0.45 — close to three times that line.
One honest note: Qmax measures first contact. The case won’t feel ice-cold for hours; what it does is keep drawing warmth away instead of storing it.
Qmax measured on Napfull fabric, [LAB NAME, YEAR]. Cool-feeling threshold per GB/T 35263-2017.

Is it cold all night?
Is it cold all night?
It feels cool the moment you lie down. After that, it keeps drawing warmth away instead of storing it, but it won’t feel ice-cold for hours. That’s how cooling fabric works, and we’d rather tell you now.
Does it help with night sweats?
Does it help with night sweats?
It can’t stop a hot flash, and nothing you sleep on can. What it changes is the surface under your head: cool to the touch and quick to dry. If night sweats are new, heavy or come without a known reason, talk to your doctor.
Why a 2-pack?

So there’s always one on the pillow and one in the wash — or one for each of you.
How do I wash it?
How do I wash it?
Machine wash cold (30°C / 85°F) on a gentle cycle with a mild detergent. Hang to dry. Skip fabric softener: it coats the fibers.
