Quinnen Williams wears XTech X2 shoulder pads.
Xtech shoulder pads are super low-profile and allow for plenty of range of motion – key for a defensive lineman like Quinnen. These pads allow him to maneuver comfortably and get to the quarterback. Also these pads super lightweight and protect his chest and shoulders against offensive lineman.
