Lots of sage advice So far.
For comfort layering is key & I like Merino wool for warmth to weight & less stink - Black Ovis & Camofire have good prices. A couple of merino light & heavy, layer to cut the wind & a waterproof layer are nice. Clothing can be antique eBay wool & 2nd hand shop stuff or ridiculous expensive. My best recent acquisitions Kuiu guide pants nice & warm with side vents, And a First Light uncomphagre puffy is very flexible. Sounds like you have good boots.
Carry game bags watch how to cut an elk up with the gutless method, they are really big compared to any deer. I bought a Mystery Ranch Sawtooth 45 this year & it looks & feels great. Lots of expensive good ones out there. OnX is worth having on the phone Use it offline & bring an extra charge battery. Elk meat is too tasty to pass up legal animals by the way.
