I like it when people give their list and then follow up with their 'primary' hunting location. It matters.
In Western Washington, it rained all the dang time (apparently true for many parts of Alaska, from what I've read.) In a place like that, the best quality rain gear you could find was pretty much up at the #1 spot. Once you were wet and miserable, the hunt was over.
In the Colorado mountains, it would get cold as Siberia when the sun dropped over the horizon, so a system of LAYERED CLOTHING that would wick sweat was #1.
In South Texas, it's the bugs that will drive you nuts so some type of bug repellent or 'head netting' rose to #1 for me, because if I'm getting bit and bothered 24/7, the hunting is suffering along with my attitude.
#2 is good boots but I'm going to ADD good, moisture wicking socks, too. I wear polypropylene (or whatever 'wonder-fabric' name they come up with for it) against my feet and - if it's going to be cold - I'll put a layer of wool sock over that. Once you get blisters, the hunt is over. Good boots help, but if you wear crappy cotton socks in them, you'll still be in trouble.
#3 is...what? So many things! How do you narrow it down to just three things? I need great clothes. I need a versatile knife. A good optic to find game is super useful. But I'm going with GPS/COMPASS. Get turned around in the rain forests of WA or the mountains of the Rockies and - well - you could die. Having some way to know where I am and how to get back to civilization has to be in there. Unless you're hunting your 'normal' spot over and over again. Then...fill the #3 spot with toilet paper. Or wet wipes. It's not only bears that dookie in the woods. (Maybe this should have been #2 because, well, you know
)
