I also dont believe to much in cover scents. I thinka deers nose is so good that it is still gonna smell you plus whatever you have on. I heard it explained on another forum once that it is like when I walk into a room with a pizza, I smell pizza. But a deer would smell tomatoes, mushrooms, onions, sausage, dough, ect. ect... Cover scents dont eliminate my scent, they just add an additional scent to it.
But that said, I still through a couple of fresh earth scent wafers in my hunting clothes tub just in case
