You can try take a look at the material blends as well with the sporting tops. Technically polyester will wick the best as it is absorbs the least moisture, which means it gets transferred to the surface of the material quickest. Nylon absorbs more moisture than polyester overall but is a stronger material.
As far as I understand polyester then does a strange thing where it retains your oils on the surface, and as your body heats up they are released somehow. Which results in the fabrics ending up smelling fairly easily if they are not treated in some way to resist this. But this is all hearsay from reading around 
So maybe for longer term low odor gear it would be in finding something with a higher ratio of nylon, with the lose then being in wicking potential. I honestly don’t have a foot to stand on here in terms of experience, but any chemical treatment I would assume wears out? Or that is definitely true for things like DWR coatings.
