Transparent umbrellas and bicycles
I love Japanese transparent umbrellas. One of the things I like the most about their design is that you can see through them; something very useful if you are in a rush, walking towards the wind and you have to tip the umbrella so you don’t get wet. Hasn’t it happened to you sometimes that with a normal umbrella you have to tilt it up to see where you are walking to? If you are riding a bicycle, as you go faster than walking, it’s almost indispensable to use a transparent umbrella if you don’t want to ride blindly 🙂 Here is a demonstration video:
