Can still find microtex really cheap if you are patient.
Microtex is great value
As far as finding "value" there is certainly opportunity out there. The major reputable brands definitely have some luxury pricing built into their business models. I pick and choose and do a lot of research to ensure when I do buy something pricier, I am paying for real performance and not marketing hype and brand coolness.
For specifics, I have a few pieces from the Russell Apx line, that was affordable stuff but not made anymore. I may be wrong but I believe King's camo bought that line out.
I like my predator polyester pants more than my sitka ascent that are twice as expensive. Polyester and fleece are good areas to save money. Little product differentiation with those simple fabrics.
Buy smart too...from now until season is the worst time to buy hunting gear. Wait until it goes on discount, hit up the pre Christmas sales and inventory clear out after Christmas.
