A nanotech based umbrella can be kept always dry, without a need to dry under sun to get rid of moisture. The umbrella when given a good shake, will be clean and moisture free right away. Even in light-coloured fabric, it will keep looking smart and as original for years. This moisture free effect is made possible by the rough nanostructure on the surface of the umbrella. Dirt and moisture simply roll off because of a much smaller surface area, to which things can stick than on a smooth surface. The moisture does not penetrate the fabric and so there is no tedious drying. This process was developed in Switzerland.
