As Greg stated; "your friends are wrong". The suits may help lower your scent, and I believe they do. They don't however get rid of your scent all toghether and nothing ever will. I have worn my full scent lock and had deer go down wind of me and not smell me....or enough of me to get alarmed and keep walking. I've had it on and had deer stop and sniff and turn around and walk away and leave because they were not comfortable because they smelled enough of me. I've had deer slam on the breaks and blow and bolt away with my scent lock on because they smelt all of me at that point. It all depends on wind, thermals, heat, raining, not raining, light wind, stong wind, moring hunt, evening hunt and many other factors. Thats why its called hunting. Your buddies are ignorant to think they are now invicible to deer because of scent lock. Its to bad they are wrecking your spot because of this. Good luck
