Leading, impact reducing soft-shell helmet cover



The Guardian Cap is the leading soft shell helmet cover engineered for impact reduction. It brings a padded, soft-shell layer to the outside of the decades old hard-shell helmet and reduces impact up to 33%.



Guardian Caps are worn by 300,000+ athletes nationwide to reduce impact during practice and in games.

Stay up to date with the latest announcements & teams using Caps.


Worn by 300+ colleges, 3000+ high schools, 750+ youth programs, All 32 NFL Teams, and All 9 CFL Teams

Mandated by the NFL for 2024 contact practices.

Permitted by the NFL to wear in games if the player choses to do so.


“We’ve got two years of data now showing significant concussion reductions in those players that wear Guardian Caps in the NFL,” said Dr. Allen Sills, MD, FACS, Chief Medical Officer of the NFL. “We might actually see a Guardian Cap on a player in a game this year.”

“It’s really become a norm here. The players know the Caps. They’ve seen the data, it works. The Guardian Caps have become another piece of equipment that they take to practice. You think about all the head impacts that we’re reducing from players wearing them and it’s second nature now.” 

Brendan Burger, Equipment Director of LA Rams

“We have tested Guardian Caps in labs and have seen significant reduction in the impact forces that the head sees when the Guardian Cap is on the helmet. It is very promising in the lab and on the field.”

Ann Bailey Good, PhD, Senior Mechanical Engineer, Biocore, LLC

“We have expanded the mandate to all players with the option for quarterback, kicker, and punter.  There is also the option for the player to wear it in the game if he so chooses”

Dawn Aponte, Chief Administrator of Football Operations at the NFL

“We’re trying to take head contact out entirely in some fashions. The Guardian Cap has been a very important change for us as it’s shown to reduce impact. It has been very effective and reduced concussions by 52%.”

Roger Goodell, Commissioner of the NFL

“We actually started using the Guardian Caps several years ago on a couple of specific position groups on a trial basis.  While we realize there is no piece of equipment that will prevent all concussions we pride ourselves on injury prevention and anything that may help us keep our student-athletes a little safer on the field is welcome.  It was an adjustment for some of the players initially, but eventually the caps just became part of their daily equipment.  We have expanded their use to multiple position groups now and of course to anyone who specifically requests a cap.  Common sense that adding this extra, non-invasive layer to the helmet lessens the amount of force generated during head-to-head or head-to-ground contact.  While there is no way to know how many concussions we have prevented, we definitely believe in the product and will continue to use it on our players.”

David Gable, MS, ATC, LAT, Associate Athletics Director Sports Medicine at TCU

“Exceeded our expectations.” (When commenting on Guardian Caps and how the NFL preseason saw a more than 50% reduction in concussions versus the previous three-year average)

Jeff Miller, NFL Executive Vice President of Health and Safety Initiatives

Practice has been wonderful. It has been healthy, it’s been safe, it’s been sound, all thanks to Guardian Caps.”

Deion Sanders, NFL Hall of Famer

“I don’t think people realize how much you practice. For every game, there are at least 20 practices. Most guys experience trouble during practice. It’s a beautiful thing to see Guardian Caps come about.”

Champ Bailey, Former UGA & All-Pro NFL Football Player

“It’s substantial. It’s really important and led to a very low number of preseason concussions compared to previous years.  So, you’ll be seeing a lot of the Guardian Cap this coming year. And we think that’s going to advance player safety substantially — not just against concussions, because we know that’s one metric. but against the repetitive head impacts that players take. Each one, in this case, with the Guardian Cap worn, is going to decrease the risk. That’s really important for the long-term benefit of the player and something the committee took very seriously.”

Jeff Miller, NFL Executive Vice President of Health and Safety Initiatives

“The Guardian Cap provided that extra layer of protection you needed during practice. The last thing you want is to lose players on the offensive and defensive lines to head injuries during practice or training camp. The Cap helped reduce some of those injuries and was useful to our team last season.”

David Edwards, NFL Los Angeles Rams OL

“We currently have some clubs using them,” “(Through testing) we’ve found some beneficial aspects with some of the hits, a reduction in force. At the high school level, it can be an important component, but it’s got to be one component of the overall strategy of reducing contact. You want to think about how you practice, how contact is modified, technique. You have to make sure (the thought is not) ‘I’ve got this thing protecting my head, I can go use it as a battering ram’. You have to talk about how to not use the head. It’s a chain with many links.”

Dr. Allen Sills, NFL Chief Medical Officer
“We train to reduce injuries, we practice smarter to reduce injuries, and we use the best technology available to us to reduce injuries. At Bergen Catholic we want to put our players in the best uniforms, the best equipment, and take every measure to limit the risks of the game. We definitely believe the Guardian Cap is one of these technological improvements.”
Nunzio Campanile, Head Football Coach, Bergen Catholic High School, New Jersey
“We believe in wearing Guardian Caps to further protect our players. We treat the caps like it’s part of their everyday equipment and it’s mandatory to wear.”
Coach Matt Logan, Centennial High School, California
“People don’t really appreciate what an O-lineman and a D-lineman goes through. They’re facing impact – not only in a game, and they’re getting 80 plays in a game – but then you see how they practice. The impact on those kids…there’s impact on every snap of every play.”
Matt Campbell, Head Football Coach, Iowa State University, Iowa
“If we’re talking about putting more padding around a kid’s head on a football field, I’m all for that. I mean, it makes sense right? I have my own son in one.”
Andy Lowry, Head Football Coach, Columbine High School, Colorado 2012 AFCA Power of Influence Award Recipient
“I wanted to let you know that we had 0 concussions after our 1st order of 20. We placed 8 on the kids that had previously received a concussion and put the remaining 12 on our hardest hitters (to protect others). We will all be wearing them from now on!”
Matt Putnam, Head Football Coach, Hazel Green High School, Alabama
