Bumpbrella

The Bumpbrella is convenient in the sense that it can be inflated easily with the help of a hand pump and deflated at the pull of a handle, so it doesn't take up too much precious space. Even if you can't help bumping into people, you can spare them the poke in the eye. This continues to be true even in the dark, thanks to the three bright LEDs which allows you to see and be seen clearly.
