I guess I' m from the " Old School" . I try to be as scent free naturally and do not make a habit of using a lot of the commercial products that are available today. I keep my hunting clothes in separate containers and never wear them unless going into the woods. To me, being woods smart is more important than trying to mask my scent. The problem I see that could cause some concern is not constantly being aware of the wind. If you use any or all of these products, just don' t let your guard down...there is no substitite for always playing it smart.
