I still want to see an independent study done on the stuff, like putting on a complete scent lok suit and hiding in the woods and having a bloodhoundwork the area. If the bloodhound can't find you, then I would consider buying the stuff. I heard a couple of years ago about a guy that put on a carbon suit of some kind and then hid in a refrigerator box (I think they had 4 of the boxes ina bigfield). Then a friend turned the guys lab loose and the lab went to his owner hidden in a box every time.
A couple of weeks ago I carried my grandson to a two man ladder stand on a warm day. We walked down a road on the edge of a pine plantation to get there. After being in the tree about 30 minutes a 4 point walked the same road and literally right under the stand and out in the field without any kind of alert on his part. We had no kind of carbon suits on, just cotton blendcamo shirts and pants.
