A deer is gunna smell ya if you are up wind and on the ground. A drug dog can small a dubie ( remember those?) in a kids locker, in the jacket pocket and in a plastic bag. That deer is going to smell you're scent if you worked up a sweat on the way out. My friend had a dog that fetched lost arrows. We'd look for those arrows for 10 minutes till we got the dog and the dog would find it in 10 seconds every time. A certain jacket with the latest whizz fabric isn't going to cut it. I wouldn't doubt if a deer could even smell the scent lock spray.
