Stefon Diggs wears a Vettex Lip-Guard Mouthguard tethered to his facemask. He almost always wears it in white but occasionally mixes in grey or blue.
Vettex mouthguards are very popular throughout all levels of football because they come in a bunch of colors, they’re comfortable, and relatively inexpensive.
You can get a Vettex lip-guard mouthguard on Amazon for under $10.
