Although it looks like a plain giant plastic bag full of tubes, Raincatch actually hides a complex water purifying mechanism. The collar of the raincoat captures rainwater which is then passed through charcoal filters and a chemical purifying system. The drinkable water is then stored in pockets around the shoulders and the wearer can take sips at any time via a series of plastic tubes sticking out of the raincoat.
In some region of this world, the rain water is still clean so it’s not a big problem if you drink the rainwater directly, but due to the polluted climate drinking it without purifying it first poses a real risk to your health. but with the raincatch now you can still enjoy drinking the purify rainwater.
