It was a little cool, so I wanted it just to preserve some body heat. Wet isn't bad, but cold and wet sucks.
I agree with FYB.
This whole issue of what is good raingear depends on where you ride and how long you ride, and what your past experiences are.
I had a good two piece TourMaster that was great for most cases and I was happy with it, until an event burned into my brain in October of 2009.
6" of rain and upper 30s temps on the way down to AR from Illinois.
Rain running off my helmet and ending up going down my back...Also, cold and wet leaking through the air between the jacket and the pants...even though they overlapped.
I got a one-piece rainsuit in 2010 with a rain hoodie, so water does not go down the back, and no cold air leakage between jacket and pants. It also breathes very well so you are not steamed to death in the heat. I believe it is a TourMaster. The only thing I have found with TourMaster products is that the zipper pullers break off almost immediately. Other than that, I would give this suit a 10 out of 10.
I don't put it on unless there is a freaking downpour, as there is nothing wrong with riding through light rain in the south with my typical OLY mesh gear.
It looks funky...but I have never cared what people think, just how well it keeps me from experiencing that drenching numbing cold. I am happy with it, and will buy another again when this wears out.
