Our flagship leathers, the Classic and MicroPerf are made in house. This allows us to apply our proprietary ProTack to them and also gives us some freedom to experiment with colors. While black and natural are the standard colors, we also release a limited run of four colors throughout the year: green, navy, purple and red. These Seasonal Putter Grips will have the same performance as our Standard Putter Grips, but they'll have a contrasting stitch (instead of black). Each year, the Seasonal Putter Grips will utilize a different stitch style.
