12\"" pattern, double web open back, deep pocket, black pitchers sleeve, Kip leather palm and mesh back. Right or Left throw. Precision Kip leather is 20% lighter and tighter grained than steerhide. The Hides are harvested in Europe and tanned in Japan. The gloves are more pliable, easier to break in and have more tensile strength than our competitors glove lines. The ADU 135 combines a new mesh back with a Kip Leather pocket and web - these gloves enhance style without sacrificing performance. The mesh back provides a lighter feel and allows for an easier break-in. Kip Leather at the tips of the fingerstalls offers increased durability.
