Some of the commentators aren't sweaty, lol. I would have to leisurely stroll so slow as to barely call it hiking to avoid a sweat.
It isn't temperature management, it is sweat management, lol. I know I will get wet and plan on changing shirts and/or adding an "absorbent" mid layer that pulls moisture out of my base layer but stays warm, like merino or fleece. That can dry out in my pack as I hike or just from my body heat as I wear it.
Besides my torso, my socks are soaked through as well. Nothing I can do there so I wear merino to keep the stink down and switch them out regularly. My boots are wet inside after a couple days of good hiking in cold weather when they won't dry.
I don't get in weather much below 25. Synthetic base layer only to hike, rarely a vest that I can open and close on my front, but that is if I am stopping a little more or slowing and need to capture the heat.
Bottom line is that I just heat up and sweat like mad so merino is like wearing a wet sponge. Synthetic seems to dry more moisture out rather than hold it like merino.
I run a baseball hat, maybe something for the ears. I run a gaiter over my ears and nose if they need it. I will add merino wool pull on sleeves and merino gloves if the wind chill requires. Otherwise, blood flowing to arms and hands pulls heat out too. Anything else on my torso will get soaked. For pants, I don't run anything more than my Wranglers. I might put on thermals after ariving, or run a puffy pant.
Strategically, When I get to my location, I take off my wet base layer if it is too cold and will put on another shirt. With a clean shirt, I slowly layer on a beanie and then a light jacket or sweater as my body cools. Ending with puffy as needed. If the temps aren't too low, I just put on a Kuiu guide jacket with the pits unzipped and front open to let the moisture dry out fast.
