"The breatheable stuff is great around town or on short trips but on a thru hike like the CDT.. frankly it was outmatched by the Montana rain. I am talking hail and rain in heavy gusts of wind. I began to call it "Raintana" as everyday at 2pm on the divide was "party time". Usually it would rain ridiculously and then clear up just as the sun set and be colder than heck under a clear night sky."
Hey, Iceaxe, since I'm prepping for the CDT (SOBO) and just swapped my rain gear to a lightweight breathable jacket to save weight (pretty big base weight for this trip it seems) --- I found your comments interesting, if not unsettling.
I had been planning to use an eVent Packa at just over a pound, but when I realized that a lighter somewhat breathable jacket could also replace my windshirt, I decided to switch. Now you have me thinking of switching back ...
While I generally like ponchos fine, I'm less of a fan in "heavy gusts of wind", and in sustained hard rain I'd prefer something with sleeves.
