Take a look at the Promaster XC-M 522CK carbon fiber with two heads at Cameraland. Joel can take care of you. I have it and like the fact that it collapses to 12 inches and is light.
Kuiu merino zip off bottoms. You will thank me the first time you get hot and want to shed them. Why Sitka has not figured out zip off bottoms in beyond me.
I smell like a dead goat by noon wearing Under Armour hunting. Sitka core baselayers don't stink quite as bad for me. I use merino for the most part, especially the bottoms. You might look at Smartwool or Farm to Feet on socks.
In my opinion, any of the above would be an upgrade over the Cabelas. The Dewpoint lives in my pack. Light, doesn't take up much space and makes a good wind shell when needed. My opinion of Cabelas goes down every time I go in there. It's not what it used to be.
