RE: Hunt downwind or buy all the fancy scent free stuff?
I have been using a "Scent Lock" liner for the last 6 years. In that time I have taken my 3 biggest bucks and countless does. 2 of the bucks and several does I took downwind from me. I am also a fanatic when it comes to sent control, to the point that my hunting buddy's laugh at me. I also use an autum cover sent on my outer camo. The bucks I took down wind from me never knew I was there. I contribute that on a large part to the scent lock liner.
You can get a scent liner for around $100.
My opinion: The direction that a deer might approach you is unpredictable. Why blow the chance for the buck of a lifetime over a $100.
