Best midlayer for long sits?

[BilboBaggins]

I'm building a layering system for long sits white tail hunting. Want to be able to stay out in 0f if I need to. I'm struggling to understand which midlayer I need.

Current line up:
First lite kiln baselayer
?? Midlayer
Sitka jetstream
Feathered friends Helios puffy

Would the sitka ambient 100 line be good? Or go heavier on the base layer and get ambient 75? Seems like 3 hoods would be annoying so maybe I should get something hoodless. What would you guys pick in this layering system? I already decided I don't want to do a dedicated whitetail system like the fanatic.

For stationary hunting, have you considered a heated vest? I have mid layers like the Ambient for using on more mobile hunts, but I’m to the point where I value more heat for sitting in a tree stand or a ground blind in sub freezing whether. Before using a heated vest, I would put three of the large disposable heat packs inside the pockets of my jacket.

So I just bought the ambient 75 to serve as a mid layer. Over my core lightweight. Use as an outer layer until cold enough that I need my fanatic jacket. I wish I would’ve bought the 100. The 75 just doesn’t give me nearly as much warmth as I was hoping.

Edit, I had been using the Kuiu Peloton 200, and I’d been pretty happy with that. Just wanted something new. So that peloton line might be worth a look too

I like the Peleton 200 or the original Ambient which was 150. Depends on level of activity. Both hoodless. I hate stacking hoods.
