I know someone who has three or four different thicknesses of pure lambswool jerseys for wearing while he's cycling, at different air temperatures. It never really gets all that cold down south here at 56°N and frankly I think spending ten minutes dicking about over which jumper you're wearing for optimal performance takes a lot of the fun out of it.
That said, I'm a fat 52-year-old, and I cycle in jeans and a T-shirt, and if I start to feel cold it's a sign I'm not pedalling hard enough and I should get the boot down a bit, burn some calories.

I'm still faster than many-jerseys-guy.
