I use a bike poncho, it covers the legs, too, and limits sweating because it is open underneath. Decathlon sells them for cheap, and them works. There is also normal colors, but I prefer to be absurdly visible (I want to see who says "I didn't seen him 🙂)

Every time I use it, I'm amazed I'm dry underneath (the face gets wet).

In any case, even if I don't wear it, I'm unlikely to get soaked, when rain is not that strong. We are not made of sugar!
