The Numbrella

The Nubrella looks to me like it would be a bit useless, unless you're also wearing a raincoat, since any water diverted from your head and upper torso would just run down and soak the rest of your clothes.

However, it's nice to see people bringing new thinking to an old solution that's not been updated for decades.

Personally, I'd prefer a full body force field, which I'm sure is just around the corner.
