Well camo doesn’t make people invisible obviously, but it’s good enough to fool birds or people at a distance if there isn’t much movement.
There’s lots of photo examples of this online where entire hunter tents and hunters are very hard to discern from the forest itself which is effectively invisible if you’re deciding to take a shot or not.




You can get hunting gear that’s not camo but yes there is a lot that is.
If someone doesn’t think about it the camo will serve them better in the long run if they do decide to hunt other things so it works out.
