hey...some guys are super anal about their scent control practices...i heard of someone shaving most all of their body because hair holds scent...if your anal about scent control and have the cash, im sure people wear as much of the stuff as they can...just to catch anything the previous layer didnt lol...but, your right...if you believe it works, and wear 1 outter layer, you should be good. but the more the better i suppose??
really, the important key to the step is keeping that OUTSIDE layer clean...your body may be washed in scent free microsupernaturalpestacidespermacidal killing agents(


) and you might be wrapped in pure activated carbon...but what goods that all gunna do when your outter camo layer is smeared in dog poop, beer, vomit and womans perfume from the wild night before???
i think that is where alot of guys mess up. that outter layer is clutch...its what the wind is hitting...its going to give off MORE scent than anything else...
i really believe my outter layer truely helps...i am far from anal about scent control...but started getting more cautious...shower, keeping clothes clean, not wearing them anywhere but IN THE WOODS etc...and its noticable. no more getting winded...even when i hunt the wind, the deer seem to come in down wind, or the wind swirls right as they are in my setup...always works that way lol...but i know one thing. ive farted in my jeans on the way to my spot. about puked..NASTY. put on the scent loc and let out another one....sure enough, never smelled it...ive tested it many times in that fashion..if my farts stink that day...they STINK lol...made me a believe...but were not getting into that debate
in the end, i think alot of it is confidence and piece of mind. one less thing to sit there worrying about. and some guys feel more is better/needed....
