Wrangler pants. Wrangler performance base layers top and bottom. Amazon basics puffy and if you're feeling frisky amazon has a mid weight and polar weight quarter zip fleece that's really really good for 22$.
If it were me the layer I'd spend the most on is your base layers, socks and boots and then pants if you feel like it.
However,
Wrangler outdoors Pants, wrangler outdoors performance baselayer and a wrangler outdoors full synthetic quarter zip, an Amazon basics puffy and a marmot rain jacket and you could hunt just as hard as I do in gear that costs a lot more than that entire setup.
Think about what you spend the most time in when you're hunting. You're always in your boots, and you're always in your base layers. After that, your pants, and then your mid layer and all layers above that.
Since a guy really needs flexibility for October weather and you don't know if you're going back don't blow all your money on one single piece of kit.
What other types of hunting do you do?
