I also assmuned that most hunting wear these days were UV Free. However, I still scan most of my hunting clothes with a Blacklight, just to make sure!

I actually have the Blacklight installed in the garage so my fiber optic sights will glow when I shoot indoors but it works great to test clothing as well.
Then what brands of clothing have you found to not be UV free, if any ?
