Where will you be riding, and over which temperature ranges? Since you already have cycling jackets, you understand the concept of layering. My "winter" outer layer on my coldest rides is a Hincapie team Wind-Tex jacket that I purchased about a decade ago. It's not heavy, but it definitely stops wind and breathes on its back. The fabric is akin to Gore fabric, in that liquid water will not penetrate it.

But it's too warm to wear above 35 degrees F, it simply cooks you after 30 minutes. I wear it over a wicking tech base layer and a thin wool sweater - down to about zero degrees F. Beneath that, the middle layer must be thicker wool. Also, beneath zero F, it's the extremities that are hard to keep warm much over an hour's ride or so.
