If there was a competition for the weirdest looking umbrella, then this must be it! In fact, this umbrella is difficult to see because the canopy is not just invisible it does not exist with the Air Umbrella.
This is a design from Je Sung Park & Woo Jung Kwon and the idea is that the adjustable pole blows out a stream of air that can actually prevent the rain from getting through. It is battery powered so as long as the rain is not too heavy and the batteries are fully charged, you should remain dry.
Unfortunately, this is a concept design and is not available to buy, but it should be!
