If you've ever been stuck outside during a rainstorm and your umbrella was blown inside out by the wind, we understand your frustration. What's worse is when you get caught in the rain wearing your favorite clothes or your phone gets wet. Smart-brella is the world's first reversible umbrella! It closes inside-out, which prevents it from getting blown out and destroyed! Another reason you need Smart-brella's reversible technology is because it helps prevent puddles and water marks from forming.
