Moisture Management and Thermoregulation...

So, we don't really have a sub-forum on clothing, and outdoors clothing various so much dependent on locations, season, climate, activity, personal preference, etc., and I wanted to narrow the discussion to backpacking. Again, these definitions can vary as well, but I’m interested in those who typically do 10-12+miles per day for 5+day trips. Since locations and seasons vary, I’m looking at 30-90 degrees; knowing weather/climate, elevation, and terrain make a significant impact. At lower temps, you’re either moving or you’re briefly “static” when setting up your shelter, fixing a quick meal, and then changing into sleep clothes and sleeping system.

So, for my choices I vary depending on the seasonal temperature ranges. The challenges are both moisture management and thermoregulation. When temperatures, sun exposure, precipitation, humidity, and wind all fluctuate to some degree daily, your added aerobic exertion as well as periodic breaks make that moisture management and thermoregulation the real challenge.

I’m curious about choices for core (upper body) mid-layers. I’m a hot hiker. I can put on a damp merino wool T-shirt when it’s 45-50 degrees as long as I’m on the trail and moving to warm up. If temps are still cool and I’m static for more than 15-20 minutes, I do feel a significant cool down/chill, especially if it’s windy. For colder temps (30 degrees or just those extended cold mornings), I’m considering a breathable wind-shirt or a microgrid pullover top. Both dry relatively quickly, but the wind-shirt would likely do better with the higher humidity we face down here. When static of course, I can pull on my rain shell or if it’s colder weather, I’ll have a long-sleeve shirt and/or a puffy vest/jacket.

Some options I'm going to try out:

Patagonia Houdini pullover
Outdoor Research Ferrosi Windshirt
Patagonia R1 pullover (for colder months)
Lukesultralight...either his Argon or Epsilon wind shells (once he's recovered from injury and back on the stitching machine)

So, what do you use for your moisture management and thermoregulation for those high aerobic/exertion activities when temps are colder or just take longer to warm up?
