Co-developed with The Hong Kong Polytechnic University, Natsu Cool is your upgraded version of cooling face mask with a better cooling effect, better design and safer choice of cooling agent.

Our researches and studies indicate that the surface temperature of inner-most layer of Natsu Cool is 5-degree Celsius lower than standard mask at maximum after wearing, with the optimal breathing zone brought along by the foldable design is the key to lower down the temperature.

This additional benefit does not come along with a compromise on the safety and protection as the level of protection of Natsu Cool is indifferent to standard mask and the cooling agents applied have all passed FDA standard.
