Heat Generation for Runners

Heat is a byproduct of energy metabolism in all training or racing. As our core temperature rises, our heart rate increases and this potentially reduces your physical capacity, whether that be power or speed.

The Role of Sweat in Cooling

In response to heat, the body activates sweat to facilitate cooling through evaporation. In high humidity environments sweat evaporation becomes less efficient, hindering your body's natural cooling mechanism.

The Right Running Apparel for Heat & Humidity

Optimize your performance in hot & humid conditions by selecting HYPERMESH™ - breathable sports apparel that efficiently wicks and works in sweat. By managing your core body temperature effectively, performance is sustained and your risk of overheating is reduced. 


PURPOSE is committed to developing products that combat the effects of heat and humidity with our proprietary HYPERMESH™ fabric technology. This advanced material features a lightweight construction, exceptional breathability, and rapid sweat-wicking capabilities. These properties help maintain a cool body temperature thereby ensuring maximum performance.
