One of the most important things to remember is that you have to keep the outside of your scent lok scent free also. You have to take it off right when you get done and don't put it on untill you are just about to go out. If you wear it eating breakfast and getting gas then it will not be effective. I can't tell you how many people I see durring hunting season wearing there camo at a resturant or getting gas etc. It is amazing half these people shoot anything.
