I have only every hunted from a stand or blind for most of my life (whitetail hunting). And when cold and wintry type weather comes in, i get cold quickly. I know going out west is going to be completely different. I know there is a lot more physical action that occurs during these types of hunts. My concern is at night, even with a zero degree sleeping bag, do you guys get cold? I dont mean chilly. I mean like uncomfortable and really wanting to pack it all in and end a hunt cold. Same goes with clothing. Iv never had to buy a bunch of layers and clothes for a hunt like this. Just worried about my past experience deer hunting, and being miserable within a matter of hours
