Wilson Glove Master Craftsman Aso-san developed this pattern with a Pro Laced T- Web, an extra large thumb stall and an extra large hand opening to accommodate Josh Hamilton’s extra large hand. All of these customizations built with YAK™ Leather are perfect for players who prefer to wear their glove off the hand and with two fingers in the pinky stall – just like Josh – and need a quick break in. The Wilson® Pro Soft Yak™ baseball gloves are light, soft and made to play with unstoppable strength. Developed with Yak Leather, this glove is 3x stronger than traditional cowhide leather. Wilson Pro Soft Yak™ ball gloves were designed to give you a quicker break-in, and a soft, game-ready feel right off the shelf.
