Archery Deer Hunting Camouflage clothing designed based upon the science of deer vision to disrupt the silhouette of the hunter. Deer are red/green color blind with 20/100 vision, so they focus in on silhouettes. With most all other camos on the market, to a deer, we look like a dark blob. With WTFCAMO, the pattern has more contrast and a larger scale. This creates visual disruption of the silhouette and the deer cannot identify the hunter as one single object.
