Thanks, Im also baffled by this wool being warm-when-wet and if this holds true when the garment is completely soaked for e.g. the entire trip. Just to make my question more presice: I was not looking for recommendations on baselayers, but a principal discussion on whats the warmest concept, provided that you have to wear one wool- and one synth-layer of equal thickness. Synth innermost and Wool outside, or the other way around.
I know this depends on the conditions, duration and activity-level. Im curious about the following two scenarios:
Prolonged wet conditions (continuous rain/sleet), with 8-12 hours walking for several days, in near, but above freezing temperatures, where you will NEVER be dry while using the garments.
I know wool can hold more water before it appears wet/cold, but I wonder if the supposed warm-when-wet effect still holds true when wool is completely soaked for longer times, i.e. if wool in fact has lower conductivity when wet (in addition to slower evaporation)?
Also, would´nt the wicking of synthetics be worthless when completely soaked over prolonged periods, when new water continuously soaks the garment? Faster drying-times are not an issue when water continuously leaks through your outer shell.
And second scenario, what would be warmest when you are soaked, but precipitation stops and drying/evaporation is setting in?
I assume that when you innermost layer wicks/breathes the least (wool-innermost scenario), its easier to notice if you overheat, and thus thermo-regulate better? The whole system dries faster, since better breathing/drying-properties farther from the body, would compensate for these layers having lower temperatures (i.e. closer to the dew-point) and less "pressure"?
In the synth-innermost scenario, I suppose the outer wool layer could not keep up with the faster wicking inner-layer and thus soak more easily.
I use wool innermost myself, contrary to popular belief (if you have two different layers), but wonder if anyone have some cutting edge thermodynamic counter-intuitive insight on this matter?
