here is what I do and It works for me without having to buy into the marketing scheme

I use unscented antibacterial soap to bathe with uncented tide to wash my clothes with
now here is the little trick, pine needled and orcedar chips in your pockets

you can also put some pine needles in your pants pockets then throw them in the dryer for 10 minuites when you put them on you will smell like a pine forest[8D]

you can do the same thing with the cedar chips

the trick is not to be scent free but to smell like something the deer can recognize that way you blend in to their enviroment
you will never be able to eleminate your natural scent but you can do things to cover it up.
