When I first saw this topic post the first thing that came to mind was keeping my body core temperature up.
As far as I know nothing beats wool in surviving a cold wet night.
agreed to a point, I love my wool long johns, but prefer fleece or synthetics on the outer layers. gonna get some spark holes but oh well. If I get really soaked and it stops I can take the stuff off wring it out and be dry pdq. plus it's not as heavy as wool.
but if I was gonna do the marathon i.e. gonna have to spend 10-12 days walkin out, wool would be high on my list, but most of my wool has long been replaced with stuff that drys faster and is lighter
