That's the problem I have with the idea of carbon suits: at some point the carbon is fully saturated. The question I have is how long does that take? Yeah, I know that if you sit in a greasy gas station you're absorbing stronger odors, but that doesn't necessarily mean more molecules are being bound by the carbon (just smellier ones). At what point is the suit saturated? How do you know when you've reached that point? Deer smell far more than we do, so there is a point between when the suit is saturated for them than it is for us, right?
Too many unknowns for me to fork out that kind of money on a suit...
