Guardian Cap
[3] While much media coverage has centered on the caps' usage in the NFL, the equipment also has documented use in other professional leagues,[4] as well as the collegiate and youth levels.[3] The Los Angeles Rams became early adopters of the caps in 2021, after the team's quarterback, Matthew Stafford, injured his hand on an uncapped helmet during training camp.[16] Ahead of the 2023 season, the CFL also mandated the use of Guardian Caps during training camp and padded practices for offensive and defensive linemen, running backs, and linebackers.[3][4] In August 2023, NFL executive Jeff Miller stated on Good Morning Football that the caps could one day be worn in-game.[21] During an April 2024 webinar, NFL chief administration officer Dawn Aponte announced that the league decided on permitting players to use Guardian Caps during games if they so desired.[3] Sportswriter Mike Florio stated that "While the league would likely never put it this way, aesthetics matter," opining that the "Guardian Cap objectively doesn't look good.[13] Nate Davis of USA Today wrote that the adoption of the caps for in-game use was "something of a seismic shift as it pertains to game day, but players have generally embraced the padded covers attached to the outside of the helmet".[32] Another study published in the journal in 2023 suggested that the caps "may not be effective in reducing the magnitude of head impacts experienced by NCAA Division I American football players".[33] Another 2023 study, published in the International Journal of Environmental Research and Public Health found that "protective soft-shell padding did not reduce head impact kinematic outcomes among college football athletes".
