science behind it seems weak...as far as the evidence they put out to explain how it works.....i am not a scientist just a student studying science...and i will agree that the microbs on us produce a lot of the "smell" coming off of us.....now weather or not silver can stop the growth (when referring to microbs it is always growth in numbers not size of a cell) i am unsure of...

but my trial tests show it makes me not smell as bad
