Instant cooling, for fourteen hours
Two-in-one cooling and ventilationIt is not an ordinary fan — it is a two-in-one cooling and ventilation unit. A wide cooling plate presses against the back of the neck while the collar circulates air around it, holding the cold where it matters for up to 14 hours.
