Hot Flashes
Hot Flashes During Menopause: What Can Pleasantly Help in Everyday Life

Sustainable cooling
Stay fresh, save resources.
Freshness doesn't have to come from a power socket. ChillNeck recharges in the fridge or cold water, needs no battery and gets reused summer after summer — instead of ending up in the bin.
Why it's more sustainable
Four reasons that count.
♻️
Reusable, not single-use
Buy once, use again and again — instead of single-use cooling pads that end up in the bin after one use.
🔌
No power or batteries
Activated in the fridge (which runs anyway) or in cold water. No battery that ages, no charger, no power use while you wear it.
🔁
Up to 300 uses
The PCM material can be re-activated again and again — with good care, across many summers.
🔋
Fewer battery gadgets
One less device that relies on a lithium battery, electronics and a charging cable — and eventually becomes e-waste.
01
Recharge without electricity
The fridge is all you need.
No battery, no charger: ChillNeck activates in the fridge (which runs anyway) or in cold water. Buy once, reuse summer after summer.
Energy compared
Cooling with a fraction of the energy.
01Reason 01
Air conditioning cools the whole room
Air conditioning draws around 1,500 watts to cool an entire room for hours — even when all you really want is to cool yourself down.

ChillNeck cools just you

Care & honest limits
How ChillNeck lasts.
🧊
Activate it right
Activate in the fridge or cold water — don't store long-term in the freezer, never microwave.
☀️
Heat & soft state
When soft, don't leave it in direct sun for long — the material could leak. Store it cooler or re-activate instead.
🧼
Keep it clean
Wipe with a damp cloth, store dry and away from light — so it lasts you many summers.
⚖️
Honest limits
ChillNeck doesn't replace air conditioning or cool a whole room — it's personal cooling on the go. The sustainability benefit comes from reuse instead of single-use and zero power use. The material is tested free of harmful substances and made for everyday use.

What is ChillNeck?
Wearable cooling — with no electricity.
ChillNeck is a neck cooling ring with PCM technology. You put it on — it cools your neck gently at around 26 °C for about 2 hours, then recharges again and again.
-
Cool & put on
Cool it down briefly (fridge, cold water — or on its own below 26 °C) and place it around your neck.
-
Gentle cooling
A steady ~26 °C cools your neck for about 2 hours — comfortable, no icy shock and no electricity.
-
Recharge
Afterwards just let it cool down again — reusable, summer after summer.
