I sweat a lot when I exercise. After an hour of running at medium intensity (~150bpm avg HR) in 20°C @ 50% humidity, I am literally drenched in sweat. I can wring my clothes and sweat will pour from it. It’s difficult to find clothes that are comfortable to wear for my long trips.
Opposite of this. Polys don’t get rid of liquids and wicking is just nonsense terminology for running down your body. You WANT the clothing to absorb the liquid. Then take the shirt off to remove it completely and then use the shirt (i prefer wife beaters) as a rag to dab your face. Polys have never made me feel fresher on my upper body than cotton cuz cotton will cool the sweat it holds.
I do wear poly shorts and boxer briefs tho as cotton in the groin does chafe.
You don’t want the fabric to wick the sweat away, you want it to evaporate off your skin, which it does very efficiently, and take the heat with it. Wet cotton is an insulator and will make you overheat.
