Bring on the rain!
I got this jacket for Christmas and I couldn't be happier. It is so lightweight and I love that it is packable into it's own pocket. I have used it several times hiking in cold rain and it has kept me dry. I can put it over my pack and it is still roomy enough to not be uncomfortable. I compete for the Wasatch Speed Goat Mountain Racing Team and it will definitely be with me as I travel and run in all kinds of weather.
