How are you? I knew someone eventually would get back with "it could be you." Skin chemistry, sweat composition, diet, etc. - all are factors. But seriously, having logged weeks in a row in tough field conditions in the military with many other guys, no showers for long periods, I can tell you, I'm at a safe low end of the spectrum. So my wife thinks too. And my wife has the same issues with synthetics that I do - some synthetics (like old polypro) stink like heck. It's a fact - some synthetics foster and hold odors much more than others. Also, there must be differences in the effectiveness of fabric treatments, whether sewn-in or chemically treated.
I'm just interested in which fabrics and fabric treatments (cocona, silver fibers, etc.) least foster odor-causing bacteria. Then let every man and woman deal with their body chemistry and cleanliness.
I'd like to propose that we all gather some anecdotal info on materials that perform better (we already know wool does) and that BPL run a stink test.
For example, as I mentioned, I found that mesh is much more of a problem than smooth fabric.
