No rain protection whatsoever. Not sure that it's any better than just a regular windbreaker in regards to rain.
I like it, never wore it in the rain so I'll defer to other reviews that did. Great top layer with light winds and cold temps. Also very lightweight and breathable for use over a polo shirt when transiting inside/outside buildings during winter. Easily packable in luggage.
Wore it once in a moderate rain and got soaked it was like I wasn't wearing a jacket
I wore this in average rain and the rain comes right through the hood. It offered adequete protection from the wind and rain but I got wet because rain comes in right through the hood.
