How it works
Snap. Cool. Go.
One deliberate move, right when you choose. No towel, no melting ice. A switch.
Stick it on
Place the element on your neck near your thyroid, the thermostat of your body, fixed with the thin elastic sports tape.
Snap to activate
Break the element so it turns fresh inside. Cooling starts on demand, exactly at the moment you decide.
Keep pushing
The cold signal lowers your head perception, so your brain gives the green light to keep working at the same effort.
