Alvin Kamara chooses to wear a Sportstar Victory T-Rex Hurricane chinstrap on his helmet. Sportstar chinstraps are proven to absorb more contact than regular chinstraps and also look really nice. They are made with medical grade foam that is both comfortable and protective. An excellent, yet simple way to upgrade your helmet setup.
You can completely customize your own Sportstar chinstrap on DicksSportingGoods.com for $30 or get the exact one AK wears (Victory Hurricane) at Sportstargear.com for $35.
