California Governor Gavin Newsom paved the way for a big moment in the youth sports space.
The Democratic governor signed legislation Monday, Sept. 28, guaranteeing parents the right to choose additional helmet protection for their children in youth tackle football, clearing the way for the use of Guardian Caps and other soft-shell helmet attachments.
Assembly Bill 708, authored by Assemblymember Avelino Valencia (D-Anaheim), requires youth tackle football leagues, youth sports organizations and coaches to allow players to use safety equipment, including soft-shell helmet add-ons. The law protects families who want their children to wear the additional padding, which is designed to absorb impact during collisions.

The legislation comes as Guardian Caps have become increasingly visible at the professional and collegiate levels, with football organizations exploring ways to reduce the risk of head injuries.
“Soft-shell helmet add-ons provide an additional layer of protection and are already used at the collegiate and professional levels, including the NFL,” Valencia said in a statement released by Newsom’s office. “Parents should have the ability to choose this technology for their children, regardless of where they play, especially during these critical years of cognitive development.”
The NFL introduced Guardian Caps during practices in 2022, initially requiring offensive and defensive linemen, tight ends and linebackers to wear them during part of the preseason. The league reported that those position groups experienced a more than 50% reduction in concussions during the mandated period compared with a three-year historical average.
The NFL has since expanded their use, and players are now permitted to wear the padded shells during regular-season games. In 2025, the league saw increased adoption of Guardian Caps and other high-performing helmet models, with 56% of players choosing helmet models that the NFL identified as offering top-level protection, including models designed to be worn with Guardian Caps.
At the college level, Guardian Caps have also appeared in practices and games, with various collegiate players implementing them. Missouri defensive end Darris Smith became the first player to wear one last year with Mizzou.
Newsom's signing builds on California's existing youth football safety requirements, including limits on full-contact practices and standards for helmet reconditioning and recertification. AB 708 also addresses concerns about helmet warranties and safety certifications when soft-shell attachments are used, with provisions taking effect Jan. 1, 2027.
