This feels way too much like science class.

No $hit!
I bought a ScentLok liner when they first came out. There was a small booth at a Hunting show in Virginia and I layed down the cash. I wore it for a few years, and bought a second one so I wouldn't have to wash them that much (back then they were not very durable).
In my *experience* with the suit...it *DO* work. I had too many situations where I sooooo should have been busted and was not..sweating my ass off...downwind...situations where I could say nothing other than the famous Sherlock Holmes quote.
When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.
That said, I don't believe they eliminate scent entirely, nor do I think they can let ya hunt day in and day outdownwind all day long after walking 20 miles and eating a few cans of baked beans and some sauerkraut. But I feel based on my experience that they are effective.
