I have had my fair share of close encounters with moose when fully camoed and went un noticed. I'm a positive they either didn't notice me or didn't see me as a threat, even when staring right at me within bow range. Sure you can get animals with out it but if you are able to get just one more in your life time Because you blended into your surroundings wearing camo it is worth it to me. Bow hunting where close is a must it's only logical that being able to blend in will give you an edge at some point
