what to wear in 40 degree temps????

[Starfish]

How about Booties? I had to make an emergency purchase when my feet froze on a ride, and I wear them any time it's under 50 degrees. For me, if my feet are warm, I can tolerate the rest of it. I notice that the serious bikers in the park wear them up to 60 degrees - maybe they know something.

I wear water/windproof calientoes underneath insulating neoprene booties if it is anywhere near under 60. Same with amfib tights. I often wear lightweight tights well up into the 60s. I'm cold more or less unless it is 70 or up.
