Josh Allen wears a Sportstar T-Rex Hurricane Chinstrap on his helmet. Sportstar Chinstraps are tested and proven to be the safest chinstraps available. These chinstraps are made with a special, medical grade foam designed to absorb as much impact as possible. They look incredible, protect you more than the stock chinstraps and are a great way to upgrade your helmet setup.
You can completely customize your own Sportstar chinstrap on DicksSportingGoods.com for $30 or get the exact one Josh Allen wears (Victory Hurricane) at Sportstargear.com for $35.
