Less club slipping in your hands, very comfortable.Great product. Medium is fairly large.Am curious how big the jumbo is.The grip were easy to put on and they have made an immediate improvement to my game.Recommend!When i changed to oversize Dri-Tac Less taper grips, it really allowed me to relax my grip. In turn, i have a more relaxed, fluid swing. It really helped my game.Was very easy to put on and they look great. I had a chance the try them out afterward to play with. It was a little different feel from the traditional tapered grips. I thinking with more overall golf practice there will be a bigger benefit the new grips on.Have these grips improved my play? Not really, but that's on me. What these bigger grips have done, is give a more secure hold on the club, which allows for a more relaxed grip on the club. A more relaxed grip alleviates the forearm fatigue I was experiencing with the standard grips. Based on this alone, I expect play and accuracy to improve. I'm a beginner golfer (and I use the term 'golfer' loosely) in my late 60's, and will use every advantage available. This is one of them.These grips allow me to play on back to back days without any pain in my hands. They are soft without feeling spongy. They also remain playable in all weather conditions.
