The Wilson Mookie Betts A2K MB50 GM 12.5 inch Left Hand Throw Baseball Glove is crafted from triple-sorted Pro Stock Select leather, using only the top 5 percent of hides for unmatched quality and consistency. Lightweight SuperSkin reduces weight while increasing durability and moisture resistance. Double Palm Construction enhances pocket stability and shape retention, while rolled dual welting adds long-term support. A DriLex wrist lining keeps your hand dry and comfortable, and the Mookie Betts signature palm stamp completes this pro-level design.
