Q. Does polyester make you sweat?

Answer

Polyester doesn’t necessarily make you sweat. If you are working out, or doing some activity that causes you to perspire, then polyester t shirt will not allow for evaporation of sweat. It is in the nature of the material to resist water or moisture, and thus prevent the sweat from coming onto the fabric. Therefore, it leads to a feeling of excessive sweating and irritation. However, if you are in a relaxed mode, then you will feel comfortable in polyester t-shirts.
