When you board a packed train after a downpour, your dripping wet umbrella usually rubs against your bag, your clothes or – even worse – a stranger. By inverting the design, the wet side folds inward when closed, leaving only the dry side exposed.

And that's not all: the clever design makes it easier to open when stepping out of a car or other shelter, and when not in use the umbrella can stand upright on its own!
