Last time this came up, I asked a question about what the difference is between the scent loc/ scent blocker suits and the military surplus charcoal suits or the liners. What is the primary difference between these? Will the surplus suits/liners even work?

I'm not trying to revive any arguments about the stuff, as I don't believe anything will completely eliminate human scent. I want to reduce my scent signature as much as possible. If the surplus stuff can do the job, then there's more money to spend on other stuff.
