To be false advertising, they would have to make a promise that they couldn't fulfill.

To say "Forget the wind, just hunt" is just a simple statement that could be given to someone by anyone and means nothing.

The scent suits are a unique product. There is no way they can claim that they completely eliminate scent. On the other hand, there is no way anybody can prove without a doubt that they don't work at all. It's up to each of us to decide. People who believe it works, truly believe it, they are happy with it so good for them. People who don't believe it have the freedom to not buy it. I have some I have picked up along the way that I bought on sale. I don't use it all the time and I don't know if it really helps or not. I kill good deer with and without it. It is still good hunting clothing so I will wear it and get use from it.
