New U-V-Killer Camo is solid blaze orange but it is also camouflage and it is superior to both. It takes advantage of the huge difference between human vision and deer vision, so that while it blends into the deer's natural background to humans it will be seen as 100% blaze orange. U-V-Killer Camo is fade resistant to keep you safer, longer. U-V-Killer Camo is identified by pattern and Logo only when viewed by ultraviolet light. The invisible pattern assures you of the unsurpassed safety of blaze orange while providing superior camouflage to the eyes of game animals. U-V-Killer Camo contains no UV Brighteners so to deer it appears only as a dull yellow/brown camouflage and blends perfectly into the deer's yellow daylight world. To maintain the optical properties of your U-V-Killer Camo Vest, wash it in cool water with Sport-Wash residue-free detergent.
