Winn's new Dri-Tac LT (less taper) was designed with a less tapered profile which offers a larger lower hand diameter. This feature offers better control and lighter grip pressure. For golfers suffering from arthritis or hand injuries, the larger lower profile offers easier gripping for less pain and fatigue. Dri-Tac material provides the shock absorption, non-slip comfort and performance in all DriTac grips. Vise is required to install grips. The grip kit includes the following: - 13 grips - 13 strips of 2" double-sided grip tape - 4 ounce bottle of Dynacraft grip solvent - rubber vise clamp
