Ok, I've read enough about carbon, how about X-static and similiar clothing that claims to use silver to stop bacteria from becoming odorous? Any scientific studies known on public record? According to the manufacturers, independant research by the U.S. Military and the medical industry has confirmed the effectiveness of silver ion flux to prevent odor. Supposedly it cannot wash out because the silver ion flux is permantly integrated into the clothing fibers. I am taking it for granted it could/should help with body odors, but I am wondering if the manufacturers are using enough of the silver ion flux to be effective.
