I’m not trying to troll, I’m genuinely curious. Thinking about deer specifically, it doesn’t seem like visual camouflage would really help much when hunting them. Deer sense predators by sensitive hearing (big ears) and smell (long snout). Their eyes are on the sides of their head, so they detect motion rather than high-resolution.
So trying to blend in with the surroundings doesn’t seem to be an advantage in this case. Assuming all this, what’s the point of clothing with camo print on it?
Breaking up your silhouette is the advantage, but for deer specifically the woodland color palette isn't doing anything. However its really common to hunt more than one kind of animal, and fowl in particular have great eyesight.
That being said, plenty of old timers hunt okay in standard outdoor gear and use the environment for their concealment. The high end stuff is absolutely for the larpers.
