I have used a trick when hiking on an over-nighter for which I want to trail run. I can't avoid the sweating, but I don't want my undershirt (base layer) from wetting my middle layer.
So, I have an old merino wool short-sleeve shirt; I have cut the two vertical sides entirely underneath the arm pits. This turns it into a full length "dickey" (faul turtle neck). When I come to a stop in the evening and wait ten minutes to stop sweating, I reach down my neck and pull up and off the sweat-soaked dickey. This works great in the winter when it is too cold to strip down to remove my undershirt. (I never use a tent when bivouacing in the winter - so I don't have adequate shelter from the cold wind.)
I am realizing now by your comments and by others here, that I am over-dressed (insulated mid layer) when being mobile with exertion (trail running, bush whacking, or snow shoeing off trail).
I guess my problem has not really been about my outer layer wetting through - it is inevitable but more controllable than what I have been doing. My inner layer is also going to wet from sweating just cuz I like to move fast. My mistake is over insulating with the middle layer. I see now that this has caused me to: 1) over-heat and excessively sweat, and foremost 2) hinder the air circulation underneath to allow the sweat moistened air to ventilate out.
... I am always amazed, that despite years of practise and experience, there is still so much to learn from others. Thanks to all for you guidance.
