I think its a bit over rated. I use whatever I have, hardwoods, mossy oak, whatever. It needs to break up your outline & blend into the surroundings a bit but I think scent & movement are the real problems in getting busted. I'v had bucks come within 15 yards while I was wearing hunter orange jumpsuits that didn't know I was there before they heard "POW" & then its too late.
JMHO but I think alot of its a gimik, if they make it we will buy it. Turkeys are a whole different ball game but deer, if you can sit still & not stink will walk right by you most times.
