The umbrella is one of the most significant inventions in modern history. But when winds pick up, it’ll most likely pick up your umbrella and toss it several miles in any direction. However, with this umbrella, all of your worries are over.
A plastic curtain ensures that splashes of water from the sides don’t soak your clothes. It’ll also handle moderate gust of wind by blowing the curtain against you, anchoring the umbrella down. This is clearly a joke invention in Japan and probably nobody ever uses it, but it’s still a pretty neat idea.
