Ideal pants for bicycle commuting the rain
Which pants do you have right now? And did you enjoy that downpour yesterday? There wasn't a dry cyclist in the city, breathable pants or not. Some days we're just going to get wet.

Showers pass is made right here in portland, and I use them on all the nasty days, for me they work great http://www.rei.com/product/821425/showers-pass-roadie-event-bike-rain-pants-mens

Arc'teryx, even though I can't pronounce their name, make the top of the line holy grail rain gear. I was just looking at these for myself yesterday: http://www.rei.com/product/836409/arcteryx-micon-insulated-pants-mens
