I am qualified to tell my personal fact that ScentLok definitely works. Ever since it first came out, I was using it religiously in the field bowhunting whitetails. I use to have at least 4 garments at once. The close encounters I had with whitetails at such a close distance when the deer were straight down wind of me or crossed my scent stream as they were walking... and to not EVER have a whitetail smell me to the point where they were alarmed in the least, shows me that it does work... absolutely. However, I did not treat it like the magic pill. I did have a clean regimen. If you look above at doetrain's cleaning regimen, then step it up a tad more, plus wear ScentLok with a customized DOUBLE breath shield, you'll start to realize why it worked so well with me. I have had way too many close encounters with downwind whitetails to think it does not work. One year from Sept. to Dec. 31, I missed about 21 days of hunting. Do the math; I'm out there quite a bit enjoying nature's beauty... up close and personal.
I do not believe I need ScentLok to be successful. I downed many a deer even before ScentLok was heard of, like many here. Using scent killer products do work and if you couple that with good ol' hunting prowess and working with the wind, you're bound to get what you are after, period.
