One of the best lesson I’ve learned so far: when you arrive at the top of the mountain and you are humid (transpiration):
Remove your wet top, put your rain jacket and the wet clothing on top of it. It will be dry by the moment you arrived down the hill.
If it’s too cold: one can do as here: dry clothing, rain jacket, wet clothing.
I call that the Heinzu-method 🤓🍀
By the way: often, it’s better to have two merinos shirts than one merino and one rain jacket 😉
