A black Arizona Diamondbacks, Serape undervisor is a serious game changer. Even in a subtle place such as the undervisor, it’s hard to miss the detailing on the bubbly-colored brim. Paired with the 1998 Inaugural Season glow in the dark logo, this is a Diamondbacks hat for the ages. Bring a little pop into your life with our “Serape Bottom” fitted.
