• The PROTACK^TM treated leather forms a bond between the leather and your hands like you have never felt before. This tack supplements the pressure needed to hold the club and allows you to relax your grip. The relaxed grip gives you more control and a greater flexibility in your wrist and results in a more fluid swing.  Greater feel, increased flexibility, softer touch, a more fluid swing and - lower scores!

And More:

• Leather grips wear-in rather than wear-out. We have had many golfers tell us that one set of leather grips last longer than up to 6 sets of synthetic grips.  
• Since you are not changing grips with such frequency, you will naturally develop a more consistent grip.
• The gripping ability increases as the moisture conditions worsen - even in the rain your confidence will grow.
• Our tests demonstrate that the Shock Resistant grips have a better shock dampening capability than the rubber grips tested (see tests) - but without that spongy, pillow-like feel of synthetic rubber.
• Unlike all other wrapped grips, our grips are pre-tensioned and can be adjusted for individual feel  - one-piece synthetic grips just can't do that.
• The GripMaster grips are hand assembled from hand selected materials and components... Every step from the selection of the hides to the finished product is hand inspected.
• Five years in the making: from the elastomer for shock absorption, to the "TPR" rubber under-last materials, from the leather tanning process and PROTACK^TM chemistry, to the patented underlast and the leather tensioning system.  GripMaster has put it all together, the look, the feel, the tradition and it's genuine leather.
• Leather, it is a naturally superior material and makes a naturally superior grip!
