What testing has been done on Guardian Caps?Updated 2 months ago

We are always happy to share the latest data on Guardian Caps. The NFL is in the process of publishing their field data that shows Guardian Caps reduced their practice concussions by over 50%. It should be available within the next two months.

Attached above are two of the latest studies on Guardian Caps:

• Peer-reviewed study conducted by NFL-appointed engineers. Led to NFL’s 2022 mandate of Caps during practice for OL/DL/LB/TE
  • Article on NFL feedback so far
  • Dr. Allen Sills speaking on Guardian Caps in the NFL
  • Our blog about the NFL’s decision to expand the mandate for 2023
• Most recent independent study conducted by Stanford researchers
  • Overall, HARM (head acceleration responses metric) values were reduced in laboratory impact tests by an average of 25% at 3.5 m/s, 18% at 5.5 m/s, and 10% at 7.4 m/s. 
  • They believe, “The primary mechanism of impact attenuation is not linear force attenuation; rather it is the low surface friction and independent movement from the helmet shell that consistently redirects impact energy throughout extended use.”

We’ll continue to build our body of research to better understand how the caps relate to end injury. At this point, we know (and limit claims to) a reduction of impact. In the interim, our customers feel that the main benefit is coming from the caps better managing the repetitive, cumulative, non-concussive blows that are adding up over the course of a season/career.

Feel free to reach back out if you have any other questions.
