I haven't used it too much yet but I've seen plenty of deer when I have worn it. Never had anything down wind of me to really test the suit. Everyone has their own opinion on these suits. I think it works to some extent but there is no way it can completely eliminateyour scent. These suits are by no means a free ticket to hunt whatever stand or wind direction you want. There is no substitute for hunting the wind and storing your clothes in a scent free container and taking scent free showers. These suits are just one step in a series of steps that should be taken towards being scent free!
