I really like this jacket. The durability is incredible for how light it is. The eVent fabric really does breathe noticeably more than goretex. The hood is my favorite of any shell I've owned (vs Marmot, REI).
I got the jacket for alpine climbing (RMNP in all seasons, etc), but end up using it for everything. Here's a story that attests to the durability of the fabric: I was riding my bike down the hill to work on a chilly morning a few weeks ago, wearing the jacket, and hit a deer while going about 35 mph. I flew over the handlebars/deer and subsequently slid to a stop on my back on the pavement. The jacket was scuffed, but the damage was almost not noticeable. I was blown away. The deer was impressed too.
It is big enough to allow me to put a medium puffy underneath. I'm usually a small, got the size small, and I'm happy with the fit.
My only complaint is that the zipper is starting to fail near the bottom, after two years of heavy use.
