Sorry to hear about the bike, Greg. Sounds like you're OK, though?

Jeff, when I wear leathers and its chilly (or rainy), I'll wear a 2-piece motorcycle rainsuit, or at least a bicycle rain jacket on top. Personally, I find that if you cut out the windchill, instantly it feels a lot warmer.

I like the motorcycle or bicycle specific gear because it's: lightweight and easy to pack into a tank bag as my bikes usually have no storage, reflective to make me more visible, cut to avoid flapping in the wind when at speed, usually pretty cheap, and breathable ('cause I hate that feeling of cold clammy perspiration on the insides of stuff when taking the gear off).

I haven't worn that set-up (leathers and rain suit) in much sub-zero riding, but I lived in PDX for a year and commuted year-round on motorcycle, and it worked for me. Admittedly, I usually wore slacks and cordura overpants for commuting, and not leather bottoms.
