I have and use the Scent-Lok like of camo...great stuff and it keeps on getting better. I have had and used mine for 4 years now and have noticed seeing my deer and the deer that I have seen have been closer and less cautious. I beleive a guy can have success either with or without it, but I think it does help if you do all the steps to be as odor free as possible....shower, wash you camo in the right detergent, spray down when inthering the woods, pay attention to wind direction....etc.
