Winn Golf Grips are constructed from advanced polymer materials - not rubber. Winn grips are absorbing 65% more shock than conventional rubber grips. The result is a smooth tension-free swing and reduced hand fatigue. Winn grips are lighter than rubber grips. A lighter grip reduces the overall weight of the club and lowers the balance point to increase club speed. The new WinnPro X putter grips use a less tapered profile than traditional designs to eliminate wrist movement while delivering a comfortable, tacky feel; available in 1.18", 1.32" and 1.60" diameters and different colors.
