I own it and use it, especially while bow hunting.

Is it the Holy Grail of scent prevention? NO.

Is it worthless? NO.

I also take real care on all other clothing with scent eliminating cleaners, I am careful of when and where I put it on, I shower using scent eliminating cleaners, I use scent eliminating sprays on my equipment,I also play the wind as much as possible.

So, I am scent conscious and feel the duds do offer some level of insurance or protection but by no means rely solely upon it to make me invisible when it comes to scent detection. IMO
