Gary Sanchez got a nice little custom hook-up from All-Star who he swears by behind the dish. They did up a custom pinstriped MVP4000 for home games, and he sticks with the grey/navy for away games. Sanchez, as well as Yadi Molina, get a custom leather forehead pad installed. You can get the MVP4000 at the link.
Update 8/2019: While he now wears Nike gear, Gary hasn’t changed masks. You can get Sanchez’ face mask at Baseball Express for $290.
