I utilize a Scent-Lok liner suit and wear Scent Blocker camo over that.I am firmly convinced this system does indeed work.I'm not as concerned about deer winding me on stand(because I always try to utilize the wind) as I am about mature deer detecting my scent on the way to and from my stand,because as we all know its damn near immpossible to hunt a mature deer and not have him pattern you in a hunt or two without you ever knowing he was there.Using this system and then spraying myself nearly head to toe with Carbon Blast has truly improved my game.Any scent reduction is a good thing.
