If you are referring to activated carbon clothing, yes I believe it helps. However it is only a small part of the puzzle. If you are not bathing using odorless soap/shampoo or keeping the rest of your clothes and boots clean (scent free), then I wouldn't invest in carbon activated clothes. To be as scent free as possible takes meticulous preparation besides wearing Scent Lok clothing or spraying on coverup. I have heard the greatest source of odor is the head (hair) and breath, yet nobody seems to talk much about "bad breath". Anyone have any experience with the special made-for-deer hunting chewing gum?
