I'm not too sure about the whole camo thing.
I've taken plenty of deer with my bow wearing jeans, rubber boots, and a long sleeve shirt. (Not camo).
Everything I was wearing was washed in scent away, I showered in scent away, and sprayed some scent away on me before entering the woods.

I think they detect smell, then movement. So if you don't stink and you sit still until go time I think you have just as good a chance as someone in $400.00 worth of top name camo.
