Winter riding jacket under or over chest protector?

Hey guys, Was looking to pick up a klim or moose riding jacket for winter and was wondering what size to get. Previously I always just wore a hoodie and under armour under my Leatt chest protector but I am looking to go a little more water proof this year

Any suggestions on size or jacket?

I was just looking at gear and planning how to be warmer and dryer this winter. I think I've decided to keep my old Fly armor one more time, wear a base vest under the armor, then a mid layer either breathable or thermal, then a light jacket like the Klim Torque. I've been wearing an Xlarge dbl thermal hoody over my armor which is ok for short rides, but usually either not warm enough or too warm as the day goes on.
If you need XXlarge last year's Klim Torque is cheap at RM

So what did you decide? I'm thinking to just where a Lg fleece over my armor and add a jacket over that. The THOR phase jacket probably sz Lg, looks like it should work: http://www.chaparral-racing.com/product/thor-phase-jacket/037-2920-0418.aspx
I def want zip off sleeves, at least resistant if not proof and not too bulky or heavy. The Fox Legion jacket could work too:

Or add $100 and get the Klim Dakar, nice!, and says designed to be worn over protectors.
