I'm the same size as your girlfriend and I use the Astral WonderJacket 200. Absolutely the most comfortable jacket that I have used. I get full range of motion with my arms, without rubbing up against the jacket. Excellent design. It has zip pockets and fleece hand warmer pouches.
I like the zip front model. It makes it easier to put on over paddling jackets and you can unzip for cooling off. Cascade Outfitters has it on sale. I bought mine through them and got it within the week.
