Finally, the protection you need in a design that won't hold you back. We made the EvoShield NOCSAE® Protective Chest Guard and Shirt to give every athlete extra confidence in front of the ball. Not only is it designed to meet mandatory NCAA and NFHS guidelines and certified by SEI to meet NOCSAE's standard for protection against commotio cordis — it also lets you run and move with total freedom. Wear it under your catcher's gear to bulk up your protection at the backstop, or throw it under your jersey in case of bad hops in the infield. The chest guard MUST be worn with this shirt to adhere to NOCSAE standards.
