Sounds like a moot point because cotton chafes and synthetic doesnt. I hang up my clothes outside after I exercise (and before I have a chance to wash them) and it makes all the difference. In general, odor is not about the acute sweat - at least anecdotally, exercise sweat doesn't really smell, it's about what happens when you bunch up your clothes and let bacteria grow in them. So getting them dry and out in the sun matters more than the fabric.
