The Dri-Tac Series is our tackiest ever. Our WinnDry polymer material combines a comfortable feel with exceptional non-slip performance in all weather conditions. Rain or shine, the Dri-Tac delivers. AVS is Winn's patented single-panel wrapping method. A sheet of polymer grip material encloses the underlisting lengthwise, resulting in a vertical seam that seals the grip on the backside. AVS Technology features no overlap of materials and a virtually seamless appearance and feel! Our AVS rod grips are easy to install.
