Warsaw is their warm jacket, which sounds different than what you have (I think). It's pretty thin, insulated, wind proof front, and with just one thin layer under it's good at 45 or so. I use it, with 2-3 layers, down to whenever I stop riding, i.e. 25 deg on the road.
I've never owned any of their lighter jackets, just their thick LS jersey (but it's not wind proof).
