I believe 100% in the UV theory. The first year I started back deer hunting (after a 20 year break) I got into the area I intended to hunt (pine thicket) an hour before daylight. A bright full moon was out. I was wearing a pair of camoflauge Lee jeans and a camo sweatshirt. My pants were glowing like a neon light in the light of the full moon whereas the sweatshirt appeared completely black. (Note that the light reflected from a full moon is UV-blue) Had a doe & yearling come in around 8 am and bust me (hunting on the ground back against tree) So I move into the bushes for better concealment. Around 4 pm another doe came in, looked in my direction and immediatly saw me. The weather had turned into a gray drizzly afternoon with low light conditions, exactly the conditions that UV reflection shows up best. And now you know the whole story.
