The primary advantage (as I see it) of an umbrella over a rubber jacket or suit with a hood is convenience. It's quick to deploy and often very compact. At most, it is about the same size and shape as a cane. This product is very bulky when folded up and has a curved shape that doesn't neatly fit in to a corner.
