Wilson Showtime A800 Catchers Mitt is a 1?2 moon web. Double palm construction uses a thin, strategically cut piece of leather that is placed between the palm liner and outer shell, providing maximum pocket stability. Full leather construction includes the shell, laces, and palm liner. The aura expertly breaks in and conforms to the hand. Low profile heel gives the glove flexibility; opens up the palm and pocket, and makes it more forgiving on bad hops.
