In illinois, the answer for me is basically add more layers as it gets colder. I always want to not wear much when I'm moving, but need some extra warmth for when I am in a treestand.
I wear a set of lightweight brown pants and a green synthetic breathable tee shirt for warm weather. I usually take my camo rain pants and jacket to wear over top of that in the morning/evening tree stand sits, or in case it rains.
When it's a bit colder, I add a merino base layer top. A bit colder yet and I add merino base layer bottoms. Colder than that and I switch from lightweight pants to a set of insulated pants and add a fleece top mid layer. Colder than that and I add a puffy jacket and full-zip puffy pants.
Also switch from lightweight ball cap, to insulated ball cap, to beanie hat as it gets colder. And switch from regular boots to 1000g Thinsulate boots when it's cold and I'm hunting from a treestand. So not that much different from any other type of hunt. Layer, layer, layer.
This. To be set up from zero to 80 your going to need a few different layering strategies.
I hunt in Alabama and Ohio over a very long season. My temps my temps range from zero to 80 with mostly temps from high 20s to 60s. So the 20-60s is where I focused first then supplemented for the extremes.
My base layers top and bottoms are midweight merino wool with the tops being 3/4 zips. I have two sets for two reasons. First I hunt up to 20 days per hunt out of camps. So sooner or later one set needs washed. Second I will double those base layers up to add warmth.
My next layer is Scentlok Savanah pants and jacket. Really light and stretchy for my 62 year old fat body. I wear these without base layers in the high temp extreme range but most over my base layers. Pants are comfortable for climber stand hunting for me down to 30 with one mid base under and down in lower 20s with two base layers. The savanah jacket is worn more like a shirt than a jacket.
Next is a scent lock vest and coat. Vest can be worn separate or zipped into the jacket with is waterproof and breathable. Jacket can be worn without the vest if temps are warmer with wind, rain or sunshine. It has a hood.
Additionally I have a non hooded midweight jacket for nice days when temps are 40s to high 50s. I wear it around camp.
For the lower extremes 20s and below I have a waterproof , breathable insulated coat (parka) and bibs. I think they are a Cabelas brand fleece and dry plus set. These are twenty years old will probably last me the rest on my life as they get very little use.
I also have rain gear. Waterproof and breathable for warm wet days. Many times I wear my base layer only under the rain gear.
I have two hats. An uninsulated cap and a stormy kromer gortex lined cap.
You can get the idea. You don't have to buy the brand I did but the function could be the same.
Over the many decades of being outdoors I learned to focus first on the 90% where your gear works close to perfect. Then buy gear that supplements you out to the extremes. Your extremes gear will last you most of your life if its quality because you may not wear it that much. I have yet to find a three layer system that will carry me thru zero to 80 in rain wind and shine. But look forward to reading other hunters ideas as Im never too old to learn.
