The Schutt Air Flex Umpire Chest Protector brings out the big guns of comfort, performance, and protection, for the serious ump. This armor-plated, tough-as-nails chest protector is surprising lightweight, and loaded with advanced moisture management technology that circulates air to keep you cool and focused all game long. The trick is the advanced Brock Bead technology built into the inner fabric. These squishy beads are massively lightweight, and can absorb impacts efficiently to keep you protected from hits. They are also made mostly of air, to give you even more circulation to regulate body temperature. Combine that with the 10mm vent holes throughout the shell, and you have on cool, heavy-duty umpire chest protector to get the job done right!
