Tech suits are specialized swimsuits designed to enhance performance in competitive swimming. Made from advanced materials, these suits reduce drag in the water and provide buoyancy, helping swimmers move more efficiently. They are often used in major competitions, including the Olympics and world championships. These suits typically feature a tight fit and may include compression elements to support muscles during races. Many elite swimmers, such as Michael Phelps and Katie Ledecky, have worn tech suits to improve their times. However, their use has sparked debates about fairness and technology's role in sports.
