Hot Sleeper? 5 Science-Backed Ways Climaflip Technology Keeps You Cool Tonight
Tired of waking up sweaty at 3am, flipping the pillow like it’s going to save you? You’re not alone. If you’re a hot sleeper, your body temperature doesn’t always play nice with traditional bedding and your sleep suffers for it.
That’s exactly why we created the Resti Climaflip range: a high-performance, season-smart sleep system powered by Cooler® fabric, one of the most advanced cooling textiles in the world.
But this isn’t just marketing fluff. Cooler® fabric has been put through rigorous, standardised lab testing and the results are kind of incredible.
Here’s exactly how Climaflip helps hot sleepers sleep cooler (and the science to back it up).
1: Cooler® Fabric Pulls Heat Away from Your Skin
Cooler® is made using ICEMAX fibres, engineered to draw heat away from your body and quickly disperse it. That “instant cool” feeling you get when you touch the fabric? That’s not a fluke.
✅ Tested using:
ALAMBETA Device at the E.U. Textile and Apparel Research Center (Turkey)
What it measures:
- Thermal conductivity (how fast heat moves through)
- Thermal absorptivity (how cool it feels to the touch)
- Thermal resistance (how well it blocks heat)
- Thickness
Result:
ICEMAX fabric scored significantly higher in thermal conductivity and lower in resistance, making it faster to cool and better at releasing heat than standard PES (polyester).
Sleep stat spotlight: 62% of UK adults say overheating impacts their sleep. But most haven’t tried cooling bedding that’s actually lab-tested.
2: 360° Cooling from the Climaflip Body Pillow
Unlike standard pillows that cool on just one side, the Climaflip Body Pillow is wrapped in Cooler® fabric all the way around.
So no matter how you shift, roll, hug, or flip it: the cool side is always there.
This makes it ideal for:
- Full-body support for side or pregnant sleepers
- Night sweats, menopause, and hormonal shifts
- People who love a cooling cuddle without overheating
Bonus: ICEMAX fabric is also thinner than traditional poly blends, which means better airflow around your body.
3: Breathability Backed by ISO Standards
Staying cool isn’t just about heat, it’s also about moisture. That’s why the Climaflip collection is tested for water vapour permeability: a fancy way of saying it lets sweat escape instead of trapping it under your sheets.
✅ Tested using:
PERMETEST device
Standard: ISO 31092 (recognised worldwide for measuring breathability in fabrics)
Result:
ICEMAX slightly outperformed standard fabric in moisture wicking. It doesn’t just feel cooler—it helps keep your skin dry by allowing vapour to pass through the surface.
4: Designed for Instant Cool Touch
That immediate “ahhh” when you lie down on a Climaflip pillow or topper? That’s no accident.
Tested using:
EN 511:2006, Section 5.6
Measured at the AITEX Textile Research Institute in Spain
What it does:
Tests how cool or warm a material feels on first contact (known as “contact cold”).
Result:
ICEMAX fabric scored lower on initial touch temperature, meaning it feels cooler the moment your skin hits it.
Want that just-flipped-pillow feeling all night long? This is how you get it.
5: Passive Cooling with Zero Noise, No Plugs
Some sleep tech tries too hard: gel layers, electric fans, or mattress pads that sound like a robot wheezing. The Climaflip range is different.
It uses passive cooling scientifically engineered fabric that performs on its own, no wires, no batteries, no noise.
And it holds up over time:
- Machine washable
- No drop-off in performance
- No chemical cooling gels or temporary coatings
Lab-Tested Performance: At a Glance
