For the avid runner, there’s nothing worse than a rise in body temperature just a few miles into a run. To combat that, Nike is introducing its all new AeroReact Technology, a lightweight fabric developed by the Nike Explore Team and Research Lab alongside runners from all over the world. AeroReact is uniquely engineered to adapt to changes in a runner’s temperature. Supporting the body’s existing thermoregulation capabilities, the textile’s bi-component yarn senses moisture vapor and opens its structure to maximize breathability. The women’s Nike AeroReact Pullover Top and men’s Nike AeroReact Half-Zip are available October 1 at nike.com.
