Shark skin swimsuits are nicknames given by people based on their appearance characteristics, and their core technology is to imitate the skin of sharks. In addition, this swimsuit fully integrates bionic principles. Experiments have shown that the fibers of this swimsuit can reduce water resistance by 3%, which has extraordinary significance in swimming competitions where the outcome can be determined in 1% of a second.
