A clear inflatable umbrella. It doesn't hurt to bump into and inflates with a bicycle pump located inside the handle.
One thing though, isn't the mushroom like top more prone to tipping raindrops onto your shoulder if it pivots from the handlebar?
No wait--because it's clear, you're supposed to wear it around your head and look through it!
By turning the handle backwards, the umbrella is deflated. The three high-output LEDs illuminate decorative markings on the vinyl make it more charming.link
