umbrella

Since the past humans have been trying to improvise everything they invent, from candle to light bulb, type writer to computer and many more. Transport and buildings have great changes compared to the past however there is only i thing tat has not change and tat is umbrella. besides the material, the umbrella have not change abit and have not improvise at all. For example even if u have an umbrella in the rain , your pants, shoes and shirts will somehow get wet and there is no way u can be 100 percent dry. Is umbrella really the only object that will remain the same even after many generation?
