I'm considering testing the umbrella strategy. I'm pretty happy with my setup (Gossamer Gear Gorilla, HMG Cuben Tarp, etc.), but its time for the rain gear to be upgraded. I've been carrying a pretty heavy rain jacket. I'd like to try out hiking with an umbrella because I hate sweating so much in a rain jacket. I feel like the other benefits of an umbrella are nice for the weight too. One major concern I have is that my main jacket for warmth is down, so obviously it can't get wet. Should I pair the umbrella with a lighter rain jacket? What are your thoughts on umbrellas?
