Constructed of injected molded magnesium, the FM4000MAG, is the next evolution in umpire masks. Magnesium  is the perfect material for an extremely light weight mask (16.8 oz), high vibration damping properties, and very high durability. The bars are a bit more bladed than the All-Star Vision™ steel masks for outstanding strength and visibility.
