Foldable and transparent umbrella by Smati The French brand Smati has an extensive collection of umbrellas. Maes & Hills sells mainly foldable umbrellas. The transparent umbrella is a bestseller, which makes sense - you can see where you're walking! All umbrellas are wind resistant, the screen folds back easily and can be opened with one push on the button. After rain comes sunshine, then you fold the umbrella easily and put it in your bag or jacket.
