Yes...as a hunter I know that silver is used in clothing as a scent and bacteria eliminator. There are even sprays to eliminate odours and bacteria from your clothes, boots, blinds etc so the animals have less chance to detect you. I use a couple of different scent-free clothing products, soaps and sprays.

I am going to my hunt camp tonight for a week archery hunting for bears. I expect the SP to be much higher when I return...as long as the bears don't smell me and decide I smell tasty...
