Right or Left Hand Throw 12" pattern, Spiral-Lock web, open back with index finger sleeve, Stress-Wedge technology, and deep pocket. Designed for professional pitcher, the ASL-20 combines superior U.S. Steerhide and quality design to address the desires of a Major League hurler. Full Spiral-Lock web, index finger sleeve, and deep pocket work together to conceal the ball, finger, hand, and wrist position so as not to tip off pitches to the hitter. Stress-Wedge technology provides added protection for the palm of the hand for those hot shots back up the box. Includes Akadema's exclusive Reinforced Pocket Design and Straight-Lace Finger Design adding more strength and durability to the pocket. Hand-crafted with select U.S. Steerhide and Akadema ¼" Rawhide black lacing.
