Okay okay, I get it, as long as I own no umbrella in the shape of a sphere (which would require 4πr² with r=170cm of fabric), my life will be similar to that of a sponge.
I hate umbrellas. They just keep your top half partially dry most of the time. But then you have to avoid poking people in the eye while walking, and carry around a giant wet umbrella all day.
I’ve heard that good raincoat is far better, but I haven’t yet taken the plunge to try it. Any positive raincoat testimonials?
