Joke about it all you want. I don't care. I'll save my money for another couple sets of camo or boots or a new bow. Activated carbon is not some new miracle product. It's been used for decades for all sorts of thing, like filtering fluids, blood, air... you name it. The problem is that the filtered agent has to be forced through thecarbon by way of pumps and pressure for it to do it's work. Some old sad sack loose fitting camo garment isn't going to hack it. Not an expert at all, just worked with it for 30 years. That may be longer than you've lived, I don't know. I know enough to understand that scent control garments aresnake oil and the hunting community has bought it lock stock and barrel.
