The Wilson A2000 1679 SuperSkin baseball first base mitt, 12.5" features a single post web and a deep consistent pocket to handle throws, grounders and pop-ups at first base. The glove's black and blonde Pro Stock® leather is paired with black SuperSkin™ - a microfiber material lighter than leather but twice as durable - for elite feel and durability. SuperSkin™ is also moisture-resistant, extending the longevity of the glove and is easier to clean than traditional leather.
