Joey Bosa wears a Sportstar Victory T-Rex Hurricane Chinstrap on his Vicis 02.
Sportstar chinstraps are becoming more common in the NFL because they are proven to be safer and more comfortable. They are built with medical grade foam that looks good and absorbs contact. They’re a very subtle, but sweet upgrade. Bosa’s is an all white, unbranded version.
You can completely customize your own Sportstar chinstrap on DicksSportingGoods.com for $30 or get the exact one Bosa wears (Victory Hurricane) at Sportstargear.com for $35.
