Everyone is right about the wind, but don't you want to stack the odds in your favor.

I don't use scent-loc suits or garmits. But, I wash my cloths with scent away and dry with scent away dryer sheets. My cloths go right into a bin and out of the house and stay locked in the back of the truck. Then i wash with regular old ivory soap, and put on regular cloths. When i go hunting, I stand outside in my skibbies, and put on my hunting cloths spaying down each layer. I believe it helps.
