I have 2 waterproof jackets; one is a Performance yellow looking slicker thing and the other is a really expensive jacket (can't remember the brand). They both have pit zips. The slicker has a hood. Both are fine to wear, but i only ride in the rain if I have to (like it starts when I'm out there). Most of the time I've used them it has been cold out, so the plastic effect was minimal. I keep the pit zips unzipped most of the time. I was once caught out in a downpour last spring, when the temp. went down to 48. I had a wool shirt and tights on, with a water resistant jacket. It was the worst riding experience I've had and I only had to go about 8 miles to get back to my car. I would rather feel sweaty than get hypothermia!
