I've hunted over 50 years, killed over 300 whitetails...I have never bought any scent control clothing or washed my clothes in something special...I do buy non scent baking soda deodorant and use scent free soap during the season...On top of this, I use to smoke, on stand and have killed deer with a cigarette in my fingers...I also spend a week every year camping out with no indoor shower, sometimes wearing the same clothes a couple of days in a row...
The secret to deer not smelling you is as simple as making sure you are down wind of them...
