Under Armour's Pro Catcher's Kit includes a helmet, a chest protector, and leg guards to make sure you're taking your game to the max. The Pro Head Gear features I-Bar Vision™ to open up your field of view without removing any strength from the cage. The injected-molded ABS shell is lightweight and sturdy, with a sleek design for optimal ball deflection. The Pro Chest Protector contains signature MPZ® construction and low-rebound foam. This deadens the impact of pitches or fouls, making blocked balls easier to recover. Tough plastic inserts at the throat, shoulders, and abdomen maximize the protection. HeatGear® technology keeps you cool and dry throughout the season. Lastly, the Pro Leg Guards contain triple-knee construction that beefs up the protection and retains mobility. Built with extra-thick plastic in high-impact areas and backed with breathable mesh. With 38 ventilation ports, they're sure to disperse the heat. Junior kit fits ages 9-12 (helmet fits hat size: 6 1/4-7, chest protector: 14.5", leg guards: 13"). Senior kit fits ages 12-16 (helmet fits hat size: 7-7 3/4, chest protector: 15.5", leg guards: 14.5").
