I got this jacket for cycling and multi-day hiking and am a bit disappointed. It is at best water resistant with the zip on the sleeve allowing in water to the point it is running down my arm. It is not a very waterproof jacket, and am surprised by its lack of waterproofness in the front, I got wet only after a few minutes in riding my bike. it is probably okay if you are doing walking and light rain is comong down but those winter rains proabably will beat this jacket. I know that it is difficult to choose just from the customer reviews and I hope that I merely got a faulty one but for the cost it took to return it from Australia I am pretty unhappy.
As for the sizing: I am a women who is 5ft 4" weigh about 120lbs and I purchased the small mens. I found it quite tight around the hips and pretty roomy across the chest so if you are thinking about getting more comfort out of it I would choose the size larger than you would usually purchase.
Okay, short story, not really really waterproof, not super breathable but the under-arm zips are a good fix for that, really quite close fitting around the hips and pretty loose across the chest.
