Late to the thread here, but congratulations for getting past two pages of nay-sayers. I'm all in favor of the project. It totally makes sense to me.

On winter commutes I wear knit under layers. Why? To trap warm air next to my body.
I also wear a shell outer layer. Why? To keep cold dry outer air from whisking away that warm humid air.

Sounds like wp is doing the same thing- he's just putting the "clothing" on his bike instead.
And, unlike lobster claw gloves, wool tights and puffy booties, the blue faring is crazy cool looking.
Onward good man- with more pics.
