These pants are great. I ride year round in New England in all types of weather. I've now worn them in torrential downpours & wet snow storms & my lower half stays completely dry. I like the velcroed bottoms. They're designed to tighten up & narrow the sleeve bottom so that the pant bottoms don't interfere with the pedals or drivetrain. They are easy to don or doff without having to take you shoes off. They are comfortable & do not hinder my pedaling motion.
Got these for cycle touring when you just gotta ride in the rain. Haven't used them yet but seem nice. I'm 6' & 156 lbs - ordered medium and they fit good. Can't speak about water repellency or breathability but there is a membrane coating on the inside.
The waterproof trouser is very versatile. In addition to biking, it can be used at outside sporting/stadium events or wherever one may want to keep dry in a rain/snow environment.
