too much money to spend on something that may have already absorbed all the scent it can, by the time you buy it. plus, no way to reactivate it.
i'm sure it helps, before it gets full of scent. i would imaging that the reason it "works" so well, is because once a guy shells out all that cash, they take extra care to keep it as scent free as possible. if the same care would be taken with their regular clothes, they would probably have similar results.
i use a base layer of e-scent, to kill odor causing bacteria at the skin level, and keep the rest of my stuff as scent free as possible. spray liberally with ghost spray, and i'm good to go
