I personally don't buy into the scent control stuff that much. Can they reduce your scent, maybe, but I am not sure it can do it enough. Besides that, what did you eat? Are you chewing gum or tobacco? Did you brush your teeth? The deer will smell your breath as well as the rest of you. I do use scent free soap on the clothes and sometimes myself and scent free deo. Other than that, I try to stay downwind from them. I think the scent free craze is more about separating a hunter from his money.
