I don’t know or care if the carbon suits work. I’ve had too many people really believe in them to doubt they are completely useless. But I do believe in trying to be as scent free as you can because where I hunt the wind NEVER blows from one direction for more than 3 minutes. And deer tend to come from almost any direction. Sometimes they bust you, sometimes they don’t but I’ve killed deer down wind of me when the text books said that should have never happened.
