AeroAdapt is a new proprietary material from Nike designed to help keep athletes at their optimal temperature so that sweating, overheating or getting chilled won’t interfere with a workout. The moment this fabric senses sweat, its moisture-reactive yarns open the fabric to release body heat and let air in. The wetter the material gets, the more it opens. As the moisture evaporates, the vents close to trap body heat, helping to prevent the athlete from feeling chilled or staying wet during a warm-up or cool down. AeroAdapt will debut in five garments in the new Nike Pro Collection from the brand’s Training division.
