CC: For what it's worth living in the same city you do: I wear LS jerseys all winter. Course - I also commute all winter. I use them starting when the highs stay below 65 and then just layer under them as the temps keeps dropping. I don't use a jacket until 2 layers of jersey isn't enough - usually when the lows are around 35 - oh - and when the sun doesn't come up until mid-morning since my jacket is illumnite material. This will be my third year of commuting and I appreciat every LS jersey I own.
Also: I don't ride in the winter except to commute - it's just too cold!
