Don' t try to cover up human scent. We stink. Try to be less stinky. Shower right before you go out. Use a soap designed for removing your scent. Keep your hunting clothes clean. Don' t wear them around the house. Put them on only right before you go out. Take them off immediatly when you come back in. Store them somewhere they will not pick up odors. I keep mine hunting clothes outside in big rubber maid tubs. Sometimes I freeze my but off when I go out in the morning to get dressed and my wife thinks I am retarded but that is the price we pay.
