Also late, but my FAVORITE base layer is the PI windblock - I have 2, and wear them a lot.

However, depending on how cold it gets, and your tolerance, I find that with that base layer, and one of the Symphony jackets (that does NOT have windblock), I can comfortably ride in temps right around the freezing point - even a bit below (yes, on the road and in the woods). I have become accustomed, however, to under-dressing so that I don't overheat on a ride.

Have just recently purchased the Elite and the Pro bibs. Wore the Elites to race in a VERY HOT MTB race on Sunday (think 90 degrees and 91% humidity) and these were very comfy. The leg grippers are a bit snug on me, but not uncomfortably so. The Pros I ended up with are drop bibs - the good is that there is quick access for nature breaks - the bad is that I have a long torso, and it rides up on me, negating a bib short.

Have been away from PI for quite awhile, and just now returning due to the same program you are talking about . Pretty impressed in the advances they have made.
