My thoughts are that if I can reduce my scent impact in the woods, I am going to do it. I wash in scent free detergent and spray down fully before going out. I get winded by most deer downwind of me. The scent control (in my opinion) isn't meant to eliminate you getting winded by deer, I see it as cutting down on my human odor impact in the woods. My brother and I say it "takes the edge off."
