Depends on weather conditions for me.
I try these ays to spend as much time as possible in Florida hunting in the heat. Frig the cold,,,,i'm too old for that ! lol
I prefer the Under Armour Heat Gear for the heat, and they have a STORM pant set thats lite and water repellent,it rains daily down here. So I use more of them than just about all the others, and I own them all,,,Kuiu,Sitka are fine,UA in the heat is better, exception being the Peleton shirt by Kuiu, it dries fast as anything I ever wore, but is made for slim people. My 17 inch arms and Italian gut aren't tailor made for Kuiu. Those Kuiu guys were athletic long and lean mountain climbers,i'm short and thick low level dweller. lol
Up north ? I start with Patagonia Capilene Expedition for a base,and layer out with mid weight fleece, I like Columbia, Arteryx and a few others and I cover up with a wind proof jacket to keep the wind out. Patagonia thermal base layer pants under a thermal pants set with suspenders. I am a fan of Raven Wear. I have so many,UA is decent,but not very warm, yet, the legs don't get cold on me. I am more concerned with toes and face. Simple wool baclava over a Primos skull cap is good.
Boots for the cold ? Pac boots no dount. Socks ? I never have fond the right mix, and i'm 62 and hunting since 1970. I give up. I sumise bigger boots and thick wool socks might help, but for me ? There is no keeping the feet warm,period.
