Multiple outlets report that clothing fabric can influence how the body handles hot conditions, but experts say there is no single “best” fabric for all extreme-heat scenarios. The effect depends on factors such as fabric type, how the material manages moisture, breathability, fit, and the conditions of the environment.

The Independent frames the issue as more nuanced than a one-size-fits-all answer, emphasizing that heat stress involves both how heat transfers through clothing and how sweat evaporates. Other coverage likewise stresses that performance can vary by activity level and whether fabric keeps moisture close to the skin or helps it move away.

Taken together, the reporting highlights that recommendations are context-dependent: what works for high humidity or light activity may differ from what works for dry heat or strenuous exercise. Rather than endorsing a single material, the outlets point to a broader approach—choosing clothing that supports cooling and comfort while considering the wearer’s needs and the specific weather conditions.
