I do like to have comfortable and warm/dry hunting clothes. But that can be accomplished without buying a pant,vest, and coat that can push $700. I buy on sale and look for non major brands.
Cabela’s had some pretty good mid priced hunting clothes before bass pro ruined them. I did stock up on the Cabela’s clothes.
Most of mine came from Cabela's in the good old days, too. Many from their bargain barn. Some wool pants and shirts from some military surplus outlet.
I've hunted in 40 below and 60 degree weather and never got cold or broke a sweat by layering as needed and carrying what extra I might need in a backpack.
It's not rocket science and doesn't have to cost like it either.
