NO one is scent free. It's just smart to do the best you can. You might be able to go out smelling like a resident of the streets and kill a big buck but it's sure not increasing your odds.
I always keep a nice warm pair of bagged scent "free" Coveralls in the truckfor when I get an unexpected chance to hit the woods. It's not perfect but what the heck.
I go thru more scent spray in a season than you would think possible but it's cheap and I hope it covers some of my odor flaws..

PS.. Wife came into the bathroom at 3AM yesterday to find me putting stick deodoranton my butt and B$%#s. She thinks I'm fried.....
