Hat for collect rainwater / Hat

on Earth, a lot of places are located in arid and semi-arid areas, with uneven precipitation, whereas water is very important to inhabitants there. The concept of this design is to produce peasants' sunhats with a different material, so as to simply turn the hat upside down, them it can become a rainwater-collecting hat. My goal is helping people in arid and semiarid areas to collect rainwater more efficiently.
