If you don't have a dedicated rain bike with full fenders, you need one of these. Super light weight and installs in seconds. It's not going to keep you totally dry, but will do what the name says, save your ass.
Especially useful for seats with cutouts to help avoid that unwanted instant bidet action once the road gets wet.
