Arthur P, very intelligent post, love reading good stuff like that. There are so many ways to disect the UV debate it could be an endless one. Scent, wind, movement and matching yourpattern background are the real "get busted" issues IMO. The UV brightnersin camo mainly comes from thedye and or ink, not the fabric unless its been dyed or pre washed in a UV detergent prior to printing the pattern. Coming directly from my textile company, less UV means the inks will not last as long on the fabric, more UV makes the inks more steadfast in the fabric. I have lots of fabric printed in the US and if they usecertain dyes with UV brightners its no different than getting stuff printed in China if they use UV brightners or wash it in a UV brightenting detergent. Im not an expert on deer vision, but for the cost of the Atsko product, less than $20, it certainly cant hurt if you feel its worth the cost. I spend so much money on all kinds of hunting gadgets, the cost of UV wash is minimal in comparison to most of them.If I was getting bustedfrequently I wouldnt hesitate to try it, because every little bit helps. Although,my camo pattern has been pretty darn good to me, even after being busted moving which we tested for 3 years, thats when the vertical bark pattern really messes with the deers vision and their head, they just cant figure it out
