Stefon Diggs wears a Sportstar T-Rex Hurricane Chinstrap with cam-loc straps on his Riddell Speedflex. Diggs’ version has a white shell, white straps and white branding.
These chinstraps are the most popular in the NFL because they are proven to absorb more contact that stock chinstraps and look incredible. These are an easy and relatively inexpensive way to upgrade your helmet setup.
You can completely customize your own Sportstar chinstrap on DicksSportingGoods.com for $30 or get the exact one Diggs wears (Victory Hurricane) at Sportstargear.com for $35.
