Our flagship leather, the MicroPerf is made in house. By making the leather in house, we can absorb our proprietary, moisture activated ProTack into the leather. ProTack dramatically affects the color and performance of the leather, so our color offerings are limited. However, a few times a year, we'll blend a special color of MicroPerf to celebrate holidays and events. Seasonal Grips will be offered from a start date to a finish date, no need to time a launch. Limited Run Grips will be offered until they sell out, so get them quick.
