I have had the rain poncho for quite some time, and it saved me more than once.
But when it happened that the rain got heavy, I got my shoes and ankle completely soaked. And it was not funny 😏
So I bought a pair of light decathlon overshoes (I think btwin overshoes 900).
Today we had some serious rain and I was able to cycle 7+7 km without getting wet (excluding my face…) and without sweating (this is the real advantage of the rain poncho in respect to waterproof jacket+pants IMHO).
The catch is that where I live there are rarely strong winds, except during thunderstorms (but then I would avoid cycling into a thunderstorm anyway…).
What is your solution for rainy days?
Do you have a examples of that poncho?
The waxed cotton one ? It was some small operation in Oregon that stopped business iirc.
Otherwise I have a Cleverhood Rover, that’s neither great nor terrible.
