I've been looking at getting some ScentLok hunting pants and shirt for my spot and stalk bear hunt. Do you guys think it's worth it? Last time I went out scouting the forest I was walking down a road when I saw a bear running from me about 400 yards away... made me think if it was my scent ( I had treated my clothes with a scent killer) or sound it picked up? let me know what y'all think.
