Wore this for the first time today in the pouring rain and it is definitely waterproof! The rain just sits on top then drips off! It is not padded so ideal for spring and autumn and warmer winter days like today. If it was colder I would have needed an extra layer underneath. I am a size 8 so I ordered the 8 and the 10. The 8 was too tight across the chest and on the arms so I kept the 10. It still looks neat and does not look too big and baggy but still plenty of room for a fleece underneath if needed. I like that the zip doesn't go all the way down so it was very comfortable to drive in without having to undo it every time I got in the car. But the poppers go all the way to the bottom so it keeps your legs dry. I am tall and it goes all the way to my knees so worn with long boots or wellies it kept me dry all over! The hood could be a little bigger but that's my only criticism.
