In the sport of football (American soccer), players wear helmets as a part of their gear for safety reasons. The helmet protects players from head injuries that may occur due to the physical nature of the game, which often involves high-impact collisions. Additionally, helmets are equipped with face masks to shield the face and jaw, ensuring player safety while maintaining visibility and mobility. The helmet's design often varies to accommodate different positions and preferences, making it a crucial component of a football player’s equipment.
