AllStar CM1000TM The Donut Baseball Catcher's Training Mitt The absolute best mitt for working on quick transfer speeds. This vintage style catching mitt modernized with the All-Star black/tan leather is a tool recommended by catchers, coaches, and teams for developing the fastest transfer speeds. When received into the pocket correctly, high speed balls can be caught when transfered to throwing hand. Great for working on general receiving skills too. Balls which hit the pocket drop straight to the floor while balls missed rebound away.
