The NFL, in collaboration with the NFLPA, through their respective appointed biomechanical experts, coordinated extensive laboratory research to evaluate which helmets best reduce head impact severity.

The results of the laboratory tests are displayed on the poster below and shared with NFL players, in addition to club medical, training, coaching and equipment staffs to help inform equipment choices. Other factors, in addition to the ranking, should be considered by players when choosing a helmet, including fit, comfort, durability, player position and the player’s medical history.

In 2024, the NFL and NFLPA added three position-specific posters, displaying the rankings for top generic (all-position) helmets and position-specific helmets based on additional impact conditions commonly experienced in those positions. The posters, offered for the quarterback, offensive lineman and defensive lineman positions, help players focus on the helmets that are expected to offer them the best protection for their position.
