Mine would be the same weight as the rain runs off the 2.0 Showers Pass Jacket. Like others have said the best bet though in the rain is to keep your feet dry. This helps if you have portable fenders on with a mud flap on the bottom. I did this on a really cold ride last spring and put the front fender on the night before. I was the only one to finish the metriC ride. I WANT TO BUY SOME RAIN PANTS.
