A study described by Woolmark compared wool, cotton, viscose and polyester garments with similar fabric weight and thickness during changing conditions. Researchers used sweating manikins and human testing to investigate thermal comfort, including the rest periods that follow exercise. The reported results favoured wool within those comparisons.

Stop-and-Go Exercise Tests Examine More Than Instant Drying Speed

The proposed mechanism involves moisture absorption, heat release and slower changes in the skin's microclimate. This is broader than timing how quickly a wet swatch dries. The finding belongs to the tested garments and conditions, while an actual outdoor clothing choice still depends on fit, layers and weather.
