I have actually seen that some men hike in kilts/skirts for those airflow reasons. Seems like that would be pretty effective, although I am not sure I have the confidence for that. Then again while it would be cooler than shorts for similar sun protection, it wouldn't have much bug protection or as much sun protection as pants.

On the aspect of marathoners, the tights do add to the evaporative cooling as the sweat can evaporate instead of run off, I've found that to help, hence why I dual layer shirts even though it seems insane. I don't know how much research has been actually done, and how much is just "common knowledge" that is so often wrong. Also I can see for runners that weight and wind may be a worthwhile compromise over cooling.

interesting - i have been ruminating about that - It is hard to imagine that evaporative cooling could be greater from a layer over the skin rather than from the skin boundary. The sweat that 'runs off' the skin is sweat that does not contribute to evaporative cooling but it does not mean that evaporative cooling is not occurring from water on the skin boundary - in fact it is occurring, it is just that the excess sweat exceeds the surface tension and runs off - wasted evaporative water, as it were.....

That thing that makes you quickly erect your tent, climb into dry clothes and put on a brew.
