They aren't, but I live in a hot, humid climate where it often rains. So a scooter is not the best there. And then my workplace is right on a highway - I can take lower-speed roads to get there, but even the slowest path involves 35 MPH roads (~55 km/h), and it's longer.
To be worn, when it rains. Even when not. There are shoes, socks, trousers, shirts, shorts, slips, sweaters, jackets, even suits made out of that, or functionally equivalent stuff. Another option would be something very light to pull over, which you carry with you at all times, crumpled or folded into a volume of maybe two matchboxes, single- or multi-use. Much cheaper than than the goretchy parts, btw.
