@sundeck All I know about that is when I was younger and used to go walking or yomping. Cotton clothes are shite because they get wet and it chills you. Woolen cloths get wet, and they do not chill you. They insulate from the wind even when soaked. Maybe all that lanolin oil in the wool, I have no idea, but if you're out in wets, dress wool not cotton!

My apologies, of course! But for younger me it was a lesson that took some learning :)
