Personally I have never worn or purchased any of it and have been very successful in the field. Just remember the wind is your enemy. If you practice good scent control youll do just fine, A good pair of rubber boots help tremedously as well. I found this out last year when I finally purchased my first pair. Most of us here will agree its nocessary to use any as long as you practice good scent control, wear your rubber boots, and play the wind right and sit in a good location. Heres what I got last year when doing everythign just right, the hunt lasted 30-45 minutes. Of course the buck growl played a big part as well as good scent control and playing the wind.
