For a brief period during training camp, Cooper Kupp was testing out the Riddell Speedflex. He quickly returned to his usual Schutt F7 UR1.
The Riddell Speedflex is the most popular helmet in the NFL. The ‘Flex is the perfect blend of modern styling and top of the line protection. The shell of the helmet actually flexes (hence the name “speedflex”) to absorb impact.
You can get the Speedflex for $47o from Riddell.
