I bought the chugach jacket two years ago and wore it to Alaska for a two week hunt. I wore the coat for both heavy daily rain and just for a shell to stop wind on days when the sun actually came out. It was worn everyday of my trip.
I love it it and wouldn't hesitate to recommend it.

Kuiu does run with a very athletic cut. I normally wear 2x in everything I own from t-shirts to jackets. But with kuiu I have to get my jackets in 3x to fit properly.
