Zippper Umbrella / Umberella Or Package

We always used the umbrella on rainy days. But when we go inside the building or get on the bus, it usually wet our pants or bags and make the floor dirty because of drops on the umbrella. People may use the plastic bags, but it is not environmental friendly. And there is a way to solve the problem. Make one portion of the umbrella to become the umbrella cover, then use zipper to make it easy to open. Unzipped and in side out the cover, then you can keep drops inside.
