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 transferred 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. BREAKING IN YOUR MITT- We recommend not putting anything on the mitt to help break it in. The best way to break in your All-Star mitt is to just constantly use it.
