No. As long as I wear fresh hunting clothes each hunt(especially if I hang dry them outside in the wind)I feel really good about my scent control. Combine that with working the wind and bingo, that is good as you can get. I am not making fun of others that wear it as the clothing looks comfortable...and heck it may even work. I just didn't get into it and I am not the type of person that has the desire to take care of that type of clothing and pay that much money. Most all of my hunting clothes probably add up to the costs of just one of those ScentLok jackets.
