I’m a huge fan of the 240 Peleton. I just adjust the base layer under it for temps. Range from a Patagonia silk weight base, Aerowool, or a heavier Kuiu Merino wool. The wind blocking of the 240 just makes every other layer work better. That’s worked for me on many CO elk hunts in Oct and Nov. The next layer up is an Arc’teryx Atom. Though this year I have a Kuiu Hybrid to try.
Edit:
Base layer: Patagonia silk weight long sleeve
Mid: 240 Peleton
Light Insulation: Arc’teryx Atom
Heavy Insulation: Kifaru LPP
Rain: light rain jacket

The only shortcoming of that for my hunts is the synthetic base layer gets stinky faster. I typically take the Aerowool and the synthetic (it wads up to the size of a fist) so I can rinse the synthetic in a creek if necessary and then let dry.
I do put my money where my mouth is with the 240. I just received a hooded in Valo camo. Also have one in Vais, green, black, and a grey vest. Yes I am a fan!
