What I like about this is that since it's disposable, I wouldn't have to worry about carrying a wet umbrella with me after using it. It's also a great replacement for hotel umbrellas so that guests won't have to worry about returning them afterward.

My only concern is how durable are they? I'm sure it can withstand a little rain, but what about a heavy downpour? It's a great project, though. Hope they get the funding they need.
