"Dressing for cycling and dressing for skiing are two completely different things. You'll need to forget everything you know about dressing for winter in order to dress for cycling in winter."

Huh? I've worn exactly the same clothes for XC skiing as I do for cycling (with the exception of padded shorts and helmet). For downhill skiing, the only real difference is that a shell with full-body, breathable, wind blocking material works better for riding the chairlift. And guys generally don't wear skinny tights downhill skiing - but girls do.

I've skied in widely varying conditions. Everything from -32F at Stowe, VT to spring skiing with 50 mph winds at Taos, NM. I skied a lot before I really started riding a lot, and the knowledge I gained from clothing selections for skiing has really helped with clothing selections for cycling. I've ridden my road bike in temps as low at 17F, and lower temps on my mtn. bike. I'd probably wear my ski helmet on my mtn. bike if it had a visor.
