Kuiu is built around layering your wear - you're going to want a layer you can add and remove as your activity level changes.
If you are going sit, in clothes that are comfortable (not over-heating) when on the move, you are going to be, or are cold, - JMHO.
The Guide pant is good for walking and hiking if you spot and stalk - the hip vents actually work better for me than I expected.
It does shed light/medium rain/snow water well in my experience, but I'm not hunting deep Alaska or in Georgia swamps.
Kuiu makes several layers that you can take on and off with out having to take your boots off - which I like, I'm sure there are just as options in other brands.
I use the Kenai puffy jacket and pants as my sitting layers, they are in the day pack and go on before I sit in the stand.
The pants are full side zip, so they can taken off easy and fairly quickly - aka "The Stripper Pants" - several bad jokes there in our camp.
