I think that here in NJ we have it a little easier because depending on where one hunts it's usually going to be where deer come into contact with humans a lot. so the human scent depending on how strong it is doesn't alarm them as much, that being said I think the trick here is to just dull the human scent enough where by the time they realize the have been had, it's too late.
I use Dove soap for sensitive skin/unscented, I have done tests in the field with this soap over ten years now and am convinced that it works very well.
Though we all now know that the carbon clothes don't work, I am also convinced that they dull the human odor a bit and the deer seem to get fooled, I don't always wear them because I have found that one only needs it where needed, which is the head, mouth, hands. this is wear I always wear carbon, plus I use a spray scent killer on the outside of the garment as well, meaning I spray my carbon face mask and hat and gloves, if I don't wear the gloves (early season mostly) I spray my hands. I also use a mouth spray to kill the human odor from the mouth.
I have had five bucks under my tree at the same time, I only go up 10-18 feet depending on the leaves on the trees. this particular time I was at 16' up and I watched them for at least 15 minutes until they wondered off.
I have also been within feet of them on the ground with the wind at my back, and they haven't spooked, so I know this system works, but that is for me, don't forget, everyone chemistry is different and what works for me might not work for you, you have to try it and see for yourself.
Good luck !
