Virginia Tech Helmet Ratings™
Adult Football Helmet Ratings - May 2013
A total of 18 adult football helmet models that have been evaluated using the STAR evaluation system are included in the May 2013 Virginia Tech Helmet Ratings™. All 18 helmets included in the ratings have been made available to consumers at the time of publication. Helmets with lower STAR values provide a reduction in concussion risk compared to helmets with higher STAR values. Based on this, the best overall rating of 5 Stars has the lowest STAR value. Group rankings are differentiated by pre-determined thresholds.
Note: Any player in any sport can sustain a head injury with even the very best head protection. This analysis is based on data trends and probabilities, and therefore a specific person's risk may vary. This variation is likely dominated by genetic differences, health history, and impact factors such as muscle activation.
