^ (thanks, butz) Not really an option. In this neck of the woods there is almost always wind. Often quite a bit. Plus my ATB doesn't have fenders or mudguards so when the roads (or bicycle lanes) are wet so is my trousers. Front and back, that is.
Well, it doesn't rain that much here and when it does I'm okay with walking to the fairly nearby supermarket. With 'me' umbrella. Not a thing I dislike.. if it's once in a while.
I got myself a nice breathing rain suit, for a very reasonable price. Jacket was €15, and the trousers were about the same price. Found it on a site called plutosport. And I do indeed, not find myself soaking in sweat or rainwater after wearing it for an hour in a mild rain. It does not shield me fully from an hour long downpour, but, shields me enough then to still be fairly comfortable.
