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.
