Nike Swim is introducing Nike HydraStrong, a new high-performance, chlorine-resistant fabric designed for high-intensity training and competition. The new fabric will be featured in the majority of the Nike Swim performance swimwear line for spring/summer 2020. Nike launched HydraStrong after conducting research globally among young, competitive athletes from high school to collegiate level, which revealed that swimsuit longevity was a major concern among competitive swimmers. Nike HydraStrong is built for durability, fade resistance and shape retention throughout high-intensity training.
