You can most definetely get quality camo with quality dye being used in the garment. Some of them might surprise you. I have a fleece shirt that I thought would have a lot of UV especially since it seems to shine. However, under the bulb it had no glow at all.

You'd also be surprised what lint on a garment can dounder a blue light.

Problem is trying to get your portable blue lights into the store to compare.
