It performs very well on rainy bike commutes so far, haven't been able to get it into the snow yet. It breathes much better than any other shell I've tried and sheds water better too. Pit zips are spot on, internal pockets are clutch, sleeve length is primo, and the hood + high collar is my favorite feature. And love that it's made in the USA. Superior quality in comparison to just about any other jacket like it. Buying this jacket is a W.
