The DuraTech hybrid grip is unlike any Winn Grip before it, fusing two unique materials for ultimate feel and performance. The upper hand features Winn's proprietary rubber compound Elastom ETX, providing durability and responsivenes for longlasting, non. slip control. The slightly softer and more comfortable WinnDry XT polymer provides a tacky yet responsive feel in the lower hand, encouraging lighter grip pressure and enhanced short. game touch.
