I’m not sure I understand you. All I know is that some people like wool, others don’t (e.g. wool type, skin sensibility).

In winter, and that is for my commute, I might trade a fleece for a wool sweater (still got a bunch of them so why not use them) as a mid layer. Underneath that a base layer, sometimes a shirt in between.
