5oz (1/8") full grain leather palm pad insert dyed black. Design follows the pattern of Rawlings 'Dual-Core' system in their high-end gloves yet exceeds their standards in gauge by 3oz which is a common modification for professional players. For this piece, the padding serves as an organic, ergonomic replacement for the broken-down, twisted, synthetic mess of the factory inserts as well as firmly stabilizing the tear in the lace holes at the base of the web on both sides of glove. That lace hole tearing was created by unbalanced stress from the shifting and bunching of factory padding. Its heavy gauge and snuggly customized fitting acts as a backing board for the torn points at the base that previously had nothing to keep them in place. Vast difference in the reformation of pocket in hand with securing compromised lace holes is the most effective, cost efficient solution short of the costly service of having it machine sewn by an industrial machine capable of going through multiple layers of leather in an exceedingly tight manner necessary to sustain repetitive, high impact. Not at all an area that should ever be sewn by hand.
As far as shock resistance goes, the balance of its heavy gauge and malleability to conform to hand without compromising play of glove lends it unrivaled on the market. And the very reasoning for it being the number one upgraded modification sought out by the elite and professional player
