What’s with those bobblehead NFL helmets?

FastCompany: If you’ve been watching the NFL this season, you’ve probably noticed that a few dozen players have pretty big heads. Not in the diva sense, but literally. Take Chris Olave, the New Orleans Saints wide receiver. He wears a Guardian Cap, a padded cover on his helmet for added protection against head trauma. The trade-off is that it makes him look like he just nabbed a mushroom power-up in Super Mario. Olave, who suffered four concussions in his first three NFL seasons, has made peace with that. “Shoot, I got kids now,” he said after the Saints’ season opener. “I want to live a regular life after I’m done with football. I love my kids to death.

So, I don’t really care how it looks no more.” A detail of a guardian cap a protective cover for the helmet for Chris Olave #12 of the New Orleans Saints during the second half of a game against the Minnesota Vikings at Caesars Superdome on October 11, 2026, in New Orleans, Louisiana.

In-game concussions fell 15% to 129 in the 2024 regular season, then jumped 30% to 168 last year.

Much of that increase came on kickoffs, where a new format designed to bring back more returns sent concussions on the play from 8 in 2024 to 35 in 2025 . Since 2022, when the league made it mandatory in practice, the Guardian Cap has been the NFL’s most noticeable safety measure. It has been optional in games since 2024 , and after a design refresh this offseason, it’s showing up on game days more than ever . The tight ends and offensive players wear guardian caps over their helmets during a New England Patriots practice at Gillette Stadium on August 25, 2026.

It’s a lightweight foam shell that straps over any standard helmet. It’s designed to compress and slide on impact, absorbing force before the blow reaches the helmet’s hard shell underneath. The Guardian Cap comes in two main versions. NFL players and select college players wear the NXT, which weighs about 12 ounces.

Youth, high school, and most college players wear the XT, a lighter version that weighs about half a pound and sells for up to $89.99 . More than 500,000 athletes across all levels wear one. The company also makes versions for hockey and lacrosse helmets. The NFL allowed the cap in practice in 2020, then required it in practice for linemen, tight ends, and linebackers in 2022. By 2024, everyone but quarterbacks, kickers, and punters was required to wear a Guardian Cap in contact practices, and players could choose to wear it in games. Players hated the look from the start.

Watt, an All-Pro pass rusher, said it made him feel like a bobblehead. Jason Kelce mocked it by showing up to Philadelphia Eagles camp with bubble wrap around his cap. Jordyn Brooks, a Miami Dolphins linebacker, called them “UFO caps.” The 2024 game-day look wasn’t any better—a fabric sleeve printed with the team logo, stretched over the foam’s ridges like a shower cap on a carton of eggs. This season, the cap finally got a makeover. Running back Roschon Johnson #23 of the Chicago Bears wears a Guardian Cap in a preseason game between the Chicago Bears and the Cincinnati Bengals on August 22, 2026, at Paycor Stadium in Cincinnati, OH.
