I've been commuting in the low 30s, and while I think I finally figured out my right clothing combo for my 16 mile commute, it often takes me *hours* to warm up afterwards. As soon as I'm off my bike, changed and cooled off from the ride, no amount of hats, socks, warm sweats, coffee, help me warm up. We don't have showers at work, so that's not an option.

Any suggestions?
