I start off with heavyweight silk layer against skin, it does many things including reducing binding to reduce fatigue. Next is First Light merino wool. Sometimes a Rocky fleece layer Then a Pendelton wool shirt. Smartwool socks in Baffin booots.
Outer layer is usually Filson wool coat for silent hunting, however it can be Rivers West fleece parka or Carhartt.
Wool is low odor and wide temp comfort range or no sweat and freeze cycles.
Some of my wool articles are 2 and 3 decades old while still looking very nice. Wish the prices were the same.
oh and Stormy Kromer rancher wool hat with SKRE merino gaitor.
