The best thing is to pay attention to wind.... I place all of my hunting clothes in a rubbermaid tub after washing them in scent free detergent. I spray down with scent killer before going into the woods. in my tree I use a cover scent waffer. I use scent lok clothing but was very sucessful without it using the above method.... Again, wind, wind, wind, keep some milk weed flyers with you and watch the wind on a regular basis.
