Blacksburg, Va. (AP) — Virginia Tech continues leading the research in safer football helmets.
On Wednesday, the university released its newest safety ratings and gave one more helmet two thumbs up with the maximum 5 stars.
The Xenith X-2 joins Riddell and Rawlings as the only helmets with that 5 star rating.
The Virginia Tech Helmet Ratings for adult football helmets began in 2011 and is based on more than 2 million head collisions in high school and college football games.
Researchers say making helmets safer is not that hard.
"Right it's not rocket science," says Stefan Duma, who's with Virginia Tech BioMed Engineering-Sciences. "It's a straight forward engineering optimization problem. And what we've done is giving away the equation so all that matters is you go in your lab, spend time to redesign and optimize your padding and you have a 5 star helmet."
The entire Virginia Tech football team uses 5 star helmets.
