Its not necessary. Use to wear it but have not in the last 10 years. I Still kill deer with out it. I think its over rated in my opinion and it has been marketed as a product that will improve your ability to harvest an animal which I feel is not necessarly true. I see camo on everything now days. Guns, bows, vehicles, even saw camo toliet paper. This is over kill and turns me off. I think deep down inside people wear camo becasue they just like it rather than what advantages it might give them in harvesting an animal
