Interesting discussion and opinions.
Here is my .02.
I'll be 50 on my next birthday so comfort is #1 on my list for hunting clothing. If I'm warm and comfortable, I will move less. I also look for a material that won't squeek when I move my big butt on my stand seat to adjust for a shot. I was busted twice this year because of that, one of those deer being the biggest I have seen in my neck of woods.
Scent control and camo pattern are a tie for me. I'm only concerned with color for clothes that I turkey hunt in.....I look for patterns that are a little more open now. I like the current crop of silvermax/xscent/medallist clothing for scent control. I've said before, when I wear it, I don't stink, or at least I can't smell me. I know deer have better noses, but I still like to pull off my clothes at night and not be rancid. I agree with those that say hunt high and pay attention to the wind. There isn't a substitute for this.
But, if I had to rank what was most important to me in hunting clothing, I would say price. If I can't get it on clearance I don't want it.
