I'm sorry. I don't by the whole UV thing. I've been blogging about this boondoggle since 2008. It just ain't so.
#1) Deer have a slight sensitivity to UV, but it has been shown to have the opposite effect than what is being advertised by those on the UV bandwagon. Cervids have this ability to distinguish things like fur against bright snow. It is the absence of UV reflectivity that would be a turn-off to deer. See my weblog entry from about a year ago (9/25/2011)UV and Reindeer — finally some real science!
#2) The way these anti-UV products are marketed is to show how the product works under black light. This only shows how an object fluoresces in the visible part of the spectrum, not how it reflects actual UV light. The whole idea of this is bogus. Furthermore, the more I went down the bunny hole, I could not see where there was a real effect on the UV fluorescence of the material. Mind you, I spent A LOT of time down the basement in the dark mucking with this stuff back in 2008.
#3) I go back to what I was saying back in 2008, before I got dragged into the whole product testing fiasco:
a) If UV reflectivity of clothing were a problem, you would not be seeing much of it at dawn and dusk
b) If there is magic invisible UV rays coming off your clothes, that is not a problem if you're up a tree. In fact, it would make you look more like the sky
c) No one has done the actual scientific experiments to prove UV has any effect on hunting success.
Go look at my weblog and look in categories like "Elephant Repellant" "UV Killer" , etc. and then get back to me. Be very wary of companies selling products that purport to protect you from the unseen and the unknowable. This is all just my opinion, mind you. However, if I can get big ol' bucks coming by when I'm wearing thisUV-Radioactive clownsuit:
. . .you know there ain't much to this whole UV thing.
