Sweating is just part of the game. Limiting that when commuting to work is the key. I use a breathable soft shoft jacket from KB Cyclewerks, Its called a Nordic CX Jacket, they're cheap and work well. I was in the same boat previously wearing a light wicking base layer a mid wool layer and then a wind shell. The wind shell didn't breath and by the time I got to work, I was wearing a fish tank. I know wear a long sleeve base layer under my KB jacket and that's it. I've now worn it in temperatures down to 8 degrees Farenheit and it works great. This year I also purchased a set of Bib knickers from them that have the same material on the front, but a lycra/fleece back. They work great even when its raining or snowing.
