Salvador Perez, for several years now, wears the Rawlings Pro Preferred chest protector in an exclusive colorway. Its been replaced at retail by the Mach, available at Rawlings.com for $162-$166. Rawlings does offer a softball chest protector called the Velo which looks very similar at $126-$135.
We also saw Salvy in a special gold version at the 2015 All-Star Game. Check out more looks here.
