I think it works and doesnt work. If you have good experiences, youll swear by it. Also, if youre hunting in an area where deer are easily spooked it might help. However, unless youre covering everything, especially youre shoes, its not working. Id guess millions of deer have been shot without it, but if youve got the money to spend on it I cant imagine it would hurt. I personally dont own any scent lock clothing, but I do buy and use some of the sprays. I figure it cuts down on some odor, which could help you get just a little closer which might be the edge you need. But, I also use scent pads and false scrapes in conjunction with the odor control sprays and I also scout out my areas, try and figure out where and when the deer are moving and I always try to get in the right positions. Tons of hunters get lucky, but if you spend some time in your hunting areas, you really dont need luck or scent lock clothing. But, it cant hurt, right. Duane
