Water Drop / Product for controlling temperature and humidity

Design Concept:
It is a big issue for people on accommodating human body to the moisture of atmospheric humidity because the current big differences of global climate and temperature change everything.
There usually are more than two different types of climates in a country because of latitude designation. We do need “Water Drop” with functions to dehumidify and humidify to help accommodate to the temperature differences of places where we travel around or work for without worrying the influence of humidity changing upon our body.(Using those recycling PET bottles is to collect the solidified water molecule in the air.)
