I recently got an Outdoor Research Helium jacket. It's not really marketed as a "running jacket" ,but I got it for cold, rainy runs in my northeastern home. It got some negative reviews on the REI product page, mostly for wetting out. I had had good luck with OR jackets in the past, however, and decided to give it a shot. So far I have used it twice on miserable, cold, wet runs, and I have to report that I am happy with it. The fabric has not wetted out on me and has kept me comfortable on five-mile runs in steady rains. Granted, the inside gets a little steamy from sweat, but I expected that. It is a very packable, no-frills, rain jacket that does the job for me. It helps me get out the door when the weather looks gloomy.
