Aerodynamic helmets are specially designed headgear that reduce air resistance while cycling or racing. They feature a streamlined shape that helps minimize drag, allowing athletes to move faster with less effort. These helmets are commonly used in competitive sports like cycling, triathlons, and speed skating. In addition to their aerodynamic benefits, these helmets often include ventilation systems to keep the wearer cool. Many models also incorporate advanced materials for lightweight protection. Popular among professional athletes, aerodynamic helmets are essential for improving performance in events where speed is crucial, such as the Tour de France or Olympic Games.
