Recommendations for finishing clothing kit?

[RJC]

Hey all- looking for some input on finishing out my clothing setup. My goal is to have the gear to handle any weather condition for late season western big game hunts and treestand hunting for whitetails.

Currently I have the following pieces.

Top Half
-Kuiu Merino 125 T-shirt
-Sitka Core lightweight crew
-Sitka Core lightweight hoody
-Sitka Core Heavyweight Hoody
-Sitka Kelvin Lite Hoody
-Kuiu Teton Rain Jacket

For my top half I feel like I need to add some heavier next-to-skin layers and a jacket for cutting the wind and keeping me toasty for long sits/glassing sessions in the cold...I've been looking at both the Sitka Jetstream and the Sitka Kelvin Down WS Hoody, what would you recommend (doesn't need to be Sitka either)?

Bottom Half
-Sitka Core lightweight bottom
-Kuiu Merino 210 zip-off bottom
-Sitka Ascent Pant
-Sitka Timberline Pant
-First Lite Boundary Stormtight Rainpant

I feel like the bottom half is fairly complete with the ascents for early season and the timberlines for mid to late- again maybe some heavier next-to-skin layers for the really cold hunts or maybe a pair of puffy/down pants?

Any and all input is greatly appreciated.
