When you need to protect yourself from rogue throws and hard-hit line drives, try the EvoShield® Youth Gel-to-Shell™ Full Sleeveless Chest Shirt. With Gel-to-Shell™ technology, it molds to your body going from soft, moldable gel to hard plastic, giving you the protection you need. Upon impact, the force is dispersed through the shell rather than on you. It fits easily like a shirt under a jersey, so you're covered and still able to move freely.
