The silver stuff works marginally better than the carbon stuff in controlled testing, neither worked well or for long. Bathing in an unscented antibacterial product, and applying one to your clothing is about as good as you're going to get. I use baking soda in the wash with Sportwash, and store my hunt duds in a closet with an ozone generator, I apply Deer Dander before going out. This past season a six pointer paused directly downwind of my ground blind, he never alarmed aside from a low snort and hoof stamping, and after I made some squirrel sounds he calmly walked away.
