I have been busted in both, and watched animals cross my path with no reaction in both. My theory is, it's easy to "contaminate" your gear without realizing it, no matter what you wear, and that is what happened when I got busted. Therefore, I wear my Pronghorns and try to keep them "clean" by not wearing them outside the field, walking through streams frequently, and spraying scent-killer if the mood strikes me. One downside of leather is, they require a preservative treatment now and then, and those do smell. I try to clean and treat mine after the season ends, so the odor dissipates as much as possible by the next opening day.
