Football helmets are an important piece of safety equipment for football players. They are designed to protect the head from impact and provide a secure fit. Two features of a football helmet are the STRAP and the earhole. The STRAP is a five-letter word that refers to the adjustable band that goes around the head and fastens the helmet in place. The earhole is a seven-letter word that refers to the openings on either side of the helmet that allow sound to reach the player's ears.
