I hunt in the Big Cypress swamp in South Florida. Bow season is in September when temperatures range from lows in the high 70's to highs in the mid 90's. In addition to a rigorous scent control regimen, for the past 5 years I have also worn a silver impregnated base layer.
I do sweat a lot during the day, but when I take it off at night the silver clothing does not smell to me. In part that may be because they are made of synthetic material that also inhibits the growth of bacteria and does not retain moisture. I have seen a lot of deer down wind so I believe it helps, although it is only a part of a scent control program.
I have never used carbon clothing because it is much heavier (and hotter) than a base layer, so I can't compare the two.
