"Echo -10"
"Great bat! My daughter is 11. Had been using a ‘19 LXT -11 30/19. Bought a 31/21 Echo, for her to “work” into. Went out to cage to try it out and she was smashing the ball! Took it to her hitting lesson and continued to drive the ball. Her LXT is now retired. Very impressed with bat! Thank you Marucci!"
