> Actually, another thing. Wisdom says to layer, but if you're not actually mobile much overnight I always found fewer thicker layers to be better. i.e. a thick cable-knit jumper trumped multiple thinner layers. I suspect layers are really the solution for highly active people such as skiers, runners and so on, but if you're immobile in the cold a thick jumper helps more.

It's a matter of managing the sweat. In the winter you want to be warm up until you start sweating. Sweat in the winter freezes and makes you more cold. Layers help wick away sweat, and are easier to adjust so you don't get too hot. So, yeah, layers are much more important when being active.
