The CM3000SBT is made with the highest quality leather from All Star's Japanese Steerhide leather stock, resulting in a glove designed to handle the highest pitch velocities and last a very long time, as well as a reinforced web design.
When comparing the pocket depth of the All Star Pro Elite Series: CM3000SBT Catcher's Mitt to that of other catcher mitts with the same 33.50 inch design one will not find much of a difference. As to what catcher's mitt will have the largest pocket, that would a tie between the All Star models that are 35 inch patterns and the 35 inch Marucci Pro Founders' Series model.
A mitt is always one of personal preference. Most college catchers will use between a 32.50-33.50, depending on preference. The All Star Pro Elite Series: CM3000SBT Catcher's Mitt is a great option to get for a college catcher seeking a 33.50 inch design.
