Mans best friend knows what to do. What does a good hunting dog do right after you give it a bath?
It goes out and finds the grossest smelling thing it can to role in and get rid of that human shampoo smell.
The scent lok suit is so when you go role in dog doo, you can take it off later and it blocks that smell from getting on you, stays with the suit, but you come out fresh as a daisy.
Then ya got to wear that Xscent stuff undernieth to kill yur odors so as not to funk up the dog doo smell.

Seriously, I have Scent block pants and jacket that I wouldn't wear if they were not comfortable, quiet, breathable, waterproof, and usable through a wide range of temperatures. Other garments with out carbon but with the same qualities mentioned above are about the same in price. The carbon is pretty much a bonus in my book. I take care of it as instructed and pay no attention to the slogan, "forget the wind just hunt." I'll forget the wind when I stop breathing.
I have to say that I'm doing something right. The last deer walked right in on the same trail I walked in on. Was 40-45 yards down wind for quite a while and then walked straight in.
