EvoShield X-SRZ 2.0 MLB On Field Collection Batter's Elbow Guard For both right-handed and left-handed batters. I used this on my left arm as a right-handed batter. When molding, I tried to make it as symmetrical as possible, so it can be worn on either arm. Used once a week for 3 months. There is some dirt and fraying from use. There is one strap.
