I used wool for years climbing, hunting and working on 5 continents. I converted to synthetics and have never looked back. Hard shell pants and jackets are a vital component of my layering system and are designed to ventilate well w/ full side zip pants and pit zips on jackets.
If you are in a wet environment w/ the ability to have a fire daily wool is king because drying synthetics over a fire is problematic.
If you can live w/out camo look to the climbing/ mountaineering world for the state of the art in outdoor hard use gear.
