I don't believe it's about completely hiding my Scent but more trying to dilute it as much as possible. I use both!
Why not?
I have to wear some sort of clothing might as well be something that has a chance of helping me control/dilute my scent.
IMO it has helped me see more deer at close range the last few years while using it than before. I also follow a strict scent control regimen, and hunt the wind. I may need to only fool a deer or 2 for a few seconds
