Can I make a shameless plug? I've been reading several posts about rainwear for the commute, and researching as well. Somehow I latched onto someone's recommendation of the Showers Pass company, and ordered the Showers Pass Century Jacket. Well, today it made its maiden voyage, and to my delight and surprise I was completely dry even after a 14 mile commute in a downpour. It's incredibly lightweight - about 9 oz - and has vents in the pits and on the back that keep you from stewing in your own sweat. It's also got a pocket on the back, which is waterproof. The tall collar keeps my shirt collar dry. I was incredibly pleased. I've ordered the rainpants, now. I live in Portland, Oregon, and I was a little worried about commuting through the winter (this is my first stab at that) when it gets rainy and cold. I am worried no longer.
