Since there are so many other threads containing this exact same topic, I will not comment....what I will contribute to this thread is the fact that I was watching a hunting show the other day....of which the hosts are sponsored by scent free clothing company and also biologic....so they have done there homework and stress wearing the clothing every time you are in the field....they were in a treestand when a nice buck came towards them and all of a sudden, the buck took off when it got to the fifty yard mark....their first "on-camera" comment was "he winded us"....I say, save the money, get off the ground, and hunt the wind....
