Sports helmets are protective headgear designed to reduce the risk of head injuries during various physical activities. They are commonly used in sports such as football, cycling, skateboarding, and hockey. Helmets are typically made from durable materials like polycarbonate or fiberglass and feature padding inside to absorb impact. Proper fit is essential for effectiveness, as a loose helmet may not provide adequate protection. In addition to safety, sports helmets often include ventilation systems to keep the wearer cool and comfortable. Many helmets also come with adjustable straps and removable liners for easy cleaning. Some models are equipped with additional features, such as visors or faceguards, to enhance protection and visibility during play.
