Synthetic fabrics have improved greatly over the 25 years since I got back into cycling. The cheapish running shirts I now use are really soft and feel wonderful and yet dry very fast.
But the moment the ride is over, the synthetic clothes (shorts and shirt) come off and the cotton goes on.
If you are in a truly arid environment, cotton is fine. I might even prefer it. For shirts, that is. I’d still want regular bike shorts for riding.
