At its core, camouflage serves one primary purpose concealment. Deer, with their keen eyesight, are extremely sensitive to movement and changes in their environment. When hunters wear camo clothing, they significantly reduce their visibility, allowing them to approach their prey without alarming them. Effective camo patterns mimic the natural surroundings, incorporating colors and shapes found in the woods, fields, or wherever the hunt takes place. The right camo can mean the difference between a successful hunt and a long day in the field with nothing to show for it.
