Using an idea borrowed from Nature, the NanoNuno umbrella stays dry due to its nanostructured surface where there is a smaller surface area for things to stick to. Moisture and dirt practically fall off. Even if after coming out of the rain, there is bit of moisture on the surface, a quick shake takes care of that problem. The NanoNuno only comes in 2 colors right now: black for men and a cognac color for the ladies, and is a decent 38″ in diameter.
Price: approx $100
